List of timed missions?

timed missions mass effect 3

Does someone know which missions in ME3 are timed? I don't mean timed by "priority" missions, I'll do the sidequests first. But which are the ones timed by number of missions done (like Tuchanka:Bomb).

' src=

Only Grissom Academy and Benning are considered timed mission (the ones you must do the moment its available to you). You can do everything else including N7 missions much later after Rannoch. The way I play ME3 : Vancouver > Mars > Menae > Grissom Academy > Surkesh > Utukku > Benning > Tuchanka >Citadel > Rannoch. I like to prolong the timeline between Rannoch arc and Thessia arc so the game wouldn't feel like it ended too quickly and you won't feel like you finish most of the game without VS and Tali.

You can do Turian Platoon + Tuchanka Bomb after Priority Rannoch. It will start counting down right after you do the Platoon mission. You only miss a cutscene between Primarch and Wrex but you'll gain additional scene/dialogues with Tali and VS.

Actually, Grissom Academy: Emergency Evacuation only has to be completed before Priority: The Citadel II and Benning: Evidence only has to be completed & turned in before Priority: Tuchanka.

So I'm pretty sure Tuchanka: Bomb is the only one actually limited by missions done and not a Priority mission.


Progress-sensitive missions according to the wiki are:

Citadel: Barla Von

Citadel: Alien Medi-Gel Formula

Citadel: Improved Power Grid

Citadel: Hanar Diplomat

Grissom Academy

Tuchanka: Bomb

Benning: Evidence

Rannoch: Admiral Korris and Rannoch: Geth Fighter Squadron (both expire when not completed before Priority: Rannoch)


I don't think there are other "mission done" timed missions in ME3 aside from that one...

Personally, I usually follow this guide and I don't miss anything.

However, there are a number that you can accidentally miss due to progressing the story too far. I just missed the Kasumi cameo mission on accident because I didn't know it closed after completing Priority: Tuchanka.

I'm bummed out because now she won't be at the Citadel party... which I'm almost ready to do.

Mass Effect 3 Guide

This page contains a walkthrough for the main missions of Mass Effect 3 . Major changes in the gameplay from Mass Effect 2 are listed in the main Mass Effect 3 page , while the effects of importing a saved game from Mass Effect 2 are listed in the Save File Transfer page. For a comprehensive introduction to the mechanics of the actual fighting the player must engage in on most missions, see the combat page .

Legendary Edition: All content that was previously available only from Downloadable Content (DLC) is now included by default, but overall requirements and prerequisites for the missions and characters only available from DLC in the original game remain largely the same. Legendary Edition does feature many changes to the original Mass Effect 3, including changes to how certain equipment is obtained.

Main Plot [ ]

The following missions represent plot progression. They have no time limit, but each mission must be completed before the next becomes available.

Prologue [ ]

Act III [ ]

Note: No side missions can be completed once you begin Act III, so finish up anything else you want to finish before heading to Cerberus Headquarters.

Side Missions [ ]

These missions are issued or can be acquired as the game progresses. They are sorted according to the Priority mission after which they become available. The opportunity to complete certain side missions expires once specific main plot missions are completed. Others are marked as failed if not completed before a number of other missions are completed. These missions are noted below as "progress-sensitive missions" and "timed missions" respectively. Be aware that any side missions not completed before the main plot mission Priority: Cerberus Headquarters will no longer be accessible for the remainder of the game.

Note: Italicized mission names denote minor missions which can be completed merely through planet scanning, conversations, or finding an item during another mission.

Priority: The Citadel I [ ]

Priority: Palaven [ ]

Priority: Sur'Kesh [ ]

Priority: Tuchanka [ ]

Priority: The Citadel II [ ]

Priority: Geth Dreadnought [ ]

Priority: Rannoch [ ]

Priority: Thessia [ ]

Screen Rant

Mass effect 3: the best order to play missions (& why).

While missions in Mass Effect 3 are more regimented than in the previous games, players can ultimately decide where and how to best prepare for war.

The urgent tone of Mass Effect 3 can sometimes make every mission feel time-sensitive, and, with every main mission labeled "Priority," it can difficult to decide what should actually be prioritized. Some missions in Mass Effect 3 are extremely time-sensitive, with players facing serious consequences for failing to complete them within the time limit. In addition, some missions have additional outcomes tied to the Charm/Intimidate dialogue choices, which players will only unlock with a high enough Paragon or Renegade score. To improve this score, players can complete missions in a strategic order and save missions with demanding Paragon and Renegade checks until later in the story. When  Mass Effect: Legendary Edition  launches later this year , returning fans and newcomers alike may find themselves wondering when to complete the various main story and side missions for optimal results.

Related:  Mass Effect 3: How to Unlock The Secret Bonus Power

While there is no single right way to explore and complete missions in  Mass Effect 3 , fans generally agree there are some missions best saved for late-game to ensure the player has as many options as possible when it counts. This order generally also allows players to earn as many War Assets as possible, contributing to their military readiness rating against the Reapers and ensuring they don't lose a squadmate in the final battle. It also helps to have a plan for completing the four Mass Effect 3 DLC , which tend to be a bit more lighthearted than the rest of the story and can allow fans a moment to catch their breath in the face of so much chaos. Here's an optimal way to complete missions in  Mass Effect 3 .

Optimal Mission Order for Mass Effect 3

The optimal mission order for  Mass Effect 3  ensures players can earn enough Paragon or Renegade points to access all possible Charm/Intimidate conversation options. There are several main missions during which Shepard has to make extremely difficult calls. Completing certain side missions ahead of these main missions and having a high enough Paragon or Renegade score will guarantee Shepard has access to every possible option. Players who want all the options also should focus on getting as high a Paragon or Renegade score as they can.

Players should also keep track of their War Assets. Choices they make will affect how many War Assets they earn, and the number of Assets they have between Mass Effect 2 and Mass Effect 3 will help determine military readiness. A higher readiness score ensures survival of squadmates and affects the Mass Effect 3 ending .

Between missions, Shepard should scan planetary systems, check unread messages, and speak to all squadmates. These activities can be completed any time; however, some systems will not open until certain side missions are completed. Scans will often unearth War Assets, artifacts, and other items. Some of these will need to be delivered to individuals on the Citadel for a reward. Players can also complete various side quests for refugees and officials on the Citadel for added credits and War Assets. For some of these missions, items can be found during main and side missions. If they are missed, they can be purchased from the Specter Terminal at the Embassies. Generally, the Normandy can dock at the Citadel as often as necessary to talk to squadmates, complete side missions, or make purchases.

Players can find items for characters on the Citadel in the following systems:

It's important to note not every player will want to complete the main story of  Mass Effect 3  the same way, and there is no wrong way to order missions. Generally, the Priority missions will need to take place in a certain order. Beyond that, players can explore when and where they feel most fits their Shepard's story. The Leviathan DLC can be started early and completed later in the game, if players prefer. Additionally, it is possible to place the Omega DLC just about anywhere when players need a break from preparing for war. Side missions, especially the Citadel ones, can be ignored, though there will be a penalty to War Assets for doing so. Ultimately, players can shift missions around to make the most sense for their story and desired outcomes.

Mass Effect 3: Optimal Mission Order

With an abundance of quests available and consequences for your actions, it's always good to know the best way to tackle things.

Quick Links

Prologue: getting back in action, act 1: the genophage, act 2: the geth and quarian conflict, act 3: asari and cerberus.

Despite not being as open as its predecessor, Mass Effect 3 gives you plenty of freedom regarding mission order. You need to do nearly all of the Priority quests in a set sequence, but you have more control over when you play each secondary operation . However, there are some risks to embarking on some adventures at the wrong time . After all, several missions are time or progression-sensitive, so those are easy to fail if you're not careful .

RELATED: Mass Effect Legendary Collection: Early Game Tips For Those Starting Mass Effect 3

Mass Effect 3 is a story-heavy game, and the order you do missions can positively or negatively impact the flow of the narrative . For instance, if you've just heard about a colony under attack, then it doesn't make sense for Shepard to spend the next few hours roaming around the Citadel. Therefore, if you want a playthrough that makes narrative sense and stops you from missing out on quests , then here's a guide.

Updated on February 11, 2023, by Gabrielle Huston: There's no worse feeling in the world than missing out on something just because you altered the order of a few missions! The ripple effect means that it can have lasting consequences. We've updated this guide to make sure you know everything you need to know in order to get the results you're looking for, including recommended companions, timed quests, and DLC content.

The first few missions of Mass Effect 3 are all about the Reaper invasion and the galaxy's response to it. You are forced to play them in the order the game dictate

Mission Order:

After visiting the Citadel for the first time, the game begins to open up. You have control of the Normandy and can go anywhere that's available. This section of the story focuses on Shepard trying to acquire the help of the Turians, Salarians, and Krogan .

Optimal Mission Order:

During the second act of the game, Shepard finds themself in the middle of the strife between the Quarians and the Geth. It's up to you how their long-running conflict finally ends.

You can start a romance with a companion during this act.

Various things happen in Act Three, such as the Asari joining the war effort and Cerberus continuing to cause problems. There are not many secondary missions in this section of the game as things start to build towards the climax.

How many are there on the game?   I read the road map and it only stated that one was, but I want to make sure there arnt any more as one of the npcs said they "won't wait around"   The one in the road map was the N7 save the school kids thing.   Anyone shed some light ?

time sensitive doesn't mean they are actually timed, but that they have to be completed before doing certain other main missions as they become unavailable after. i think the missions are;

Grissom academy, this dissappears after doing one of the priority missions, but i cant remember which, so just do it before priority Sur'Kesh and you will be fine.

Attican Traverse: Krogan Team, Tuchanka: Turian Platoon, Tuchanka: Bomb, (platoon becoming bomb) all have to be done before completing priority: Tuchanka.

Rannoch: Admiral Koris, Rannoch: Geth Fighter Squadron both have to be done before priority: Rannoch.

Kallini: Ardat-Yakshi Monastery, has to be done before priority: thessia.

All the N7 missions just have to be done before priority: cerberus headquarters, but just do them as they become available so you dont forget about them. theres also a mission called Arrae: Ex-Cerberus Scientists, i dont know when it gets locked out so just do that as you get it as well.

i know this info is a bit scattered, so here is a list of the missions in order to make sure you get all important missions;

1. Prologue: Earth

2. Priority: Mars

3. Priority: Palaven

4. N7: Cerberus Lab

5. Grissom Academy: Emergency Evacuation

6. Priority: Sur'Kesh

7. Attican Traverse: Krogan Team

8. Tuchanka: Turian Platoon

9. Tuchanka: Bomb

10. Priority: Tuchanka

11. N7: Cerberus Attack

12. N7: Cerberus Abductions

13. Priority: The Citadel II

14. N7: Cerberus Fighter Base

15. Arrae: Ex-Cerberus Scientists

16. Priority: Geth Dreadnought

17. Rannoch: Admiral Koris

18. Rannoch: Geth Fighter Squadron

19. Priority: Rannoch

20. N7: Fuel Reactors

21. Kallini: Ardat-Yakshi Monastery

22. Priority: Thessia

23. N7: Communication Hub

24. Priority: Horizon

25. Priority: Cerberus Headquarters

26. Priority: Earth

27. Final Decision.

Grissom academy needs to be done before Cerberus attack the citadel.

Pretty much the rule is do all your side missions you can before you do any priority mission.

One Winged Joker

Yup, some of them are missable. I lost the one related to the son of some human ambassador... Bilal, or something. It seems that one of the main cutoffs is [spoiler=One Winged Joker]the invasion of the Citadel by Cerberus.

yeah like they said above good rule of thumb is do them as they pop up before moving ahead with the next priority missions

Mass Effect Legendary Edition mission order guide

The best mission order to get the most out of the remastered Mass Effect Trilogy, here's how to play Mass Effect Legendary Edition

timed missions mass effect 3

Jen Rothery

Updated: Dec 6, 2022

Looking for the best Mass Effect mission order for your Legendary Edition playthrough? In each game there are several main quests which take place on different planets, and these can be done in any order you like. Eventually, you unlock a clearly signposted final mission which serves as the ‘point of no return’. After this, you’re no longer able to complete other quests, meaning you might be locked out of the best endings if you haven’t been thorough enough in your questing.

Making sure you’ve completed all the quests you need before embarking on the final mission is essential, but when it comes to playing through the main game prior to this point, you can either decide for yourself which planets to visit first, or you can consult the wisdom of seasoned players who have put together recommended mission order lists for each game.

This includes recommendations on which crewmates to take with you on missions where they have unique voice lines, information on small changes that might arise if you fulfil prerequisites before a mission, and even advice to help the games’ narrative ‘flow’ better. We’ve also got tips on when to play Mass Effect DLC missions. Here’s our recommended Mass Effect Legendary Edition mission order list.

Mass Effect 1 mission order

Mass effect 2 mission order, mass effect 3 mission order.

Ashley, Wrex, and Garrus posing in the Normandy in Mass Effect Legendary Edition

The recommended Mass Effect 1 mission order is:

We recommend you head to Therum first to grab Liara. If you leave her recruitment until after Feros and Noveria, she suffers from the length of her imprisonment, and will initially treat you and your squad as hallucinations. Leave Therum until after Virmire, and she will be in a significantly worse condition when you arrive. This also prevents her from becoming a Mass Effect Legendary Edition romance option in the first game, as there isn’t enough time to get friendly with her.

If you want to see her alternate scenes, we recommend leaving her until last on a second playthrough. Poor Liara.

Whether you complete Feros or Noveria first is really up to you, although Noveria is easier, and Feros has a particularly tricky charm/intimidate check. The companions you bring are also up to you, though we recommend bringing Liara and Wrex to Noveria – Wrex has a lot to say, and Liara should be there for plot reasons.

You can complete the Bring Down the Sky Mass Effect 1 DLC as soon as you leave the Citadel for the first time – complete this whenever you feel like it.

The Virmire mission is the point of no return , so make sure you’ve completed as many side missions as possible, particularly Wrex’s Family Armor quest. Many of the side quests are referenced in later games, but if you’re skipping some, make sure to complete the UNC Rogue VI mission. You should also purchase the Elkoss Combine license at some point as this is useful in ME3.

The Illusive Man in Mass Effect

The recommended Mass Effect 2 mission order is as follows. First, we will cover the recruitment missions. Some characters have unique dialogue in these missions, so to hear the most unique content, you should make sure you’re able to take them with you.

Mass Effect 2 recruitment order:

We recommend doing Horizon at any point after getting Garrus, and bringing Miranda.

Miranda, one of the romantic options in Mass Effect

Mass Effect 2 loyalty mission order:

Collector Ship automatically triggers five missions after Horizon. The other missions – Firewalker, Project Overlord, and Normandy Crash Site – can be completed whenever you feel like breaking up the chain of loyalty missions. For plot reasons, Overlord works well later in the game, before Tali’s loyalty mission.

Reaper IFF is the point of no return , after which a timer begins. You have enough time to complete two more missions before incurring major losses, which should be Tali’s loyalty mission, and then Legion’s loyalty mission, so you can experience their full dialogue. After this, hurry over to the suicide mission, if you know what’s good for you.

Note that your choices during Tali and Legion’s loyalty missions contribute to a pivotal conversation check in ME3. Preventing Tali’s exile without incriminating her father helps you pass this check, as does destroying the geth heretics at the end of Legion’s mission. However, you can pass the check having only fulfilled one of these criteria, as long as you defuse the argument that follows the loyalty missions, and  save Admiral Koris during a mission on Rannoch in ME3. Also, bear in mind that in order to even attempt  the aforementioned pivotal check, there are additional criteria you must fulfil in ME3.

Wondering when to play the ME2 DLC? We recommend saving Lair of the Shadow Broker and Arrival until after the final mission. This way, you can unlock all of Legion’s conversations, also allowing you to get the appropriate response from Liara if you romanced her in the first game and someone else in ME2. Feel free to play LotSB earlier, though, if you miss her.

Four Mass Effect squadmates, Javik, James, EDI, and Kaidan

Our recommended Mass Effect 3 mission order is as follows – this guide presumes that all your squadmates survive ME2. You can swap a few of these around depending on how you feel you should prioritise – we’ll signpost the most important missions to complete before moving on. Every companion has unique dialogue in each mission, but we’ll mention the ones that we recommend for plot or utility reasons.

At this point, we recommend you head to the Citadel and talk to everyone, so you don’t miss out – particularly Thane, Liara, Kelly, Miranda, and Jondum Bau.

Complete all Citadel side quests before moving on.

Javik, a Mass Effect companion

You can now start a ME3 romance by talking to your squadmates.

We recommend visiting the Citadel again at this point.

And there you go – time to make a new Shepard with our Mass Effect face codes guide and start the whole thing all over again, maybe this time with some Mass Effect Legendary Edition mods  to change up your game.

Are there time-limited objectives in the game?

When I left Earth, things were going... poorly. It doesn't seem like I have much time to rally the troops before the situation is completely hopeless. There's precedent in the series for giving you only a certain amount of time to complete objectives. For instance, delaying the completion of the main quest in Mass Effect 2 could potentially cost you squadmates.

Are there certain objectives that I must complete within a certain time period to avoid damaging events in the game or harming my ending?

These come in a few forms, for example, once the mission Tuchanka: Bomb becomes available, you have until you've completed 3 more missions to finish it. After that point, you can no longer complete that mission, with all of the attendant consequences. Most other side missions will 'expire' eventually if you progress the critical path too far while neglecting them. Such expiration is the rule, not the exception .

In addition, many of the minor fetch-quests scattered about the Citadel can only be completed before certain major storyline events. In general, it's best to complete these as soon as they become available, as the NPC's involved in them can and will disappear without notice after a variety of triggers along the critical path.

From what I've seen, there are no explicitly 'urgent' missions like this along the main quest path, so, for the most part, if you do all side quests as they become available, you'll be fine. In a few cases, such as after Priority: Sur'Kesh , the critical path branches, and you must complete one of two missions before continuing. In this case, you'll generally have the option of completing both, so long as you do not continue on to the mission unlocked by completing the first of the two.

The notable 'exception' to all of this is that you should always check in on people in the Citadel, such as your wounded squadmate, as soon as possible . The window of time in which you can do so is often narrow, and your conversations with them (or lack thereof) will have serious implications as you continue with the games primary narrative.

There is one other notable consideration: If you delay certain storyline or DLC missions for too long, you may find that you don't have enough conversation opportunities with squadmates recruited after those events to unlock all of their bonus powers. This is especially easy to have happen with Tali and Javik. It may be worth doing Eden Prime and Rannoch as soon as they are available and you have completed any side missions which the completion of those will lock you out of.

A simple rule that seems to work for not missing anything is to always do the current Priority mission last , because those seem to be the main points where other missions become unavailable. In particular, completing the Priority mission on a planet with multiple missions always results in those other missions becoming unavailable.

However, there are some missions that can be obtained before a Priority mission, but require you to visit a system that has not been unlocked yet. Those will of course still be available after the Priority mission, but this means that it's not always possible to clear out your Journal completely before doing a Priority mission.

In my experience, the main one to worry about is Priority: Tuchanka , as several seemingly not very urgent side missions will become unavailable due to a surprise event that is triggered by completing this mission.

In-game dialogue will warn you when you're about to lock in to the other main checkpoint near the end of the game, so it's a lot harder to miss that one by accident.
