How to unlock the No One Left Behind achievement in The Bureau: XCOM Declassified - Definitive Guide
on commander you can't revive you squad mates only keep them from dying, take out drones first then the commanders if there are any then focus on the mutonts or sectopods be careful about outsiders elites or phantoms flanking you if you see one moving forward close to you kill it because they can tear you up if they flank you.
Stay in cover and away from enemies, on commanders you're guys can't do crap with their guns so i recommend equipping them with a backpack that increases their ability range or their health.
When you or one of your agents is stabilizing someone you can't be hurt so that helps, I suggest you have a recon guy and give him the distraction ability and if you or your other agent goes down have the recon guy send out a distraction before stabilizing your agent because everyone will focus on him, I stabilized a guy with a mutont standing on him doing this. you should always try to be the one to stabilize you guy because it is much more likely you AI will get downed trying to get to the downed guy than it is for you to be.
If you fail and one of your guys dies simply reload the checkpoint, it's not too difficult and it sucks to lose a high level agent anyway especially on commander so I don't know why you wouldn't load if one your guys died anyway.
Important to note if all of you go down or you die and you get the load screen this does not invalidate the achievement.
This is my first guide so please don't be harsh and tell me if there's anything I can do to improve my guide.
When one of your agent is downed, you have a certain time to revive them, otherwise they will die. The goal is simple, dont let this happen at all.
I recommend to level up as soon as you can 2 agents to Rank 5 and take only them to the fights. If any of them happens to die, just reload the last checkpoint. Having support classes could also help, having a few boosting abilities, but with the reload as a viable option it is absolutely not a must.
Keep healing as much as you can and revive if downed, to avoid too much backtracking.
It will unlock after you finish the last major operation.
But I just got this achievement after I beat the Hangar 6 R&D campaign on rookie and without anyone bleeding out. So that's cool...
(in this case the Agent is already dead but it gives you the idea)
Immediately run up to him (or have your third teammate do it) and when prompted hold to fix him back up. The Agent will be ready to get back into the fight after the 3 second reviving sequence.
Only on Commander difficulty it works a bit different. Here you will just stabilize him. He will be out of order for the rest of that firefight but come back up immediately after you killed the last alien.
This can also be done in the Hangar 6 R&D dlc.
Missable!
When you or one of your agents run out of health, they will be placed in a downed state that will require a revive. As long as you revive prior to "Bleeding" out or Reload Last Checkpoint, this trophy will be given at the end of the game.
If you are playing on Commander difficulty your agents will be "Stabilized" instead of revived until combat is over. A stabilized agent does not count as a death toward this trophy.
Even on the higher difficulties this really isn't that difficult. Try to keep the squadies close to you, having them just follow you is usually good enough. While reviving a fallen character, the reviver is completely invincible, running out in the open to save a downed team mate viable. Carter's medic ability will completely refill the bleed out bar of any downed agents. If one of your agents does die, just reload the last checkpoint.
