Red Faction

Missable.

This is in the Executive Suites area, after you go through the Underwater Research. This trophy begins from the moment you reach Gryphon (where Nothing to See Here would unlock if you stealth your way through Underwater Research). You have to escort Gryphon through one area until you get your envirosuit back to unlock this trophy. You can kill guards and civilians while doing this, just as long as no one activates an alarm. You can do this on any difficulty but on higher difficulties, the guards will detect you from a greater distance so the path may vary slightly. I recommend you save while you're doing this in case you make a mistake so that you don't have to redo the whole sequence.

Do the following to get through it safely:

1. Once you're escorting Gryphon, leave his office and you will see a guard blocking your way forward. Jump in the fountain to lure him forward, then kill him from behind when the guard in the corridor you went through is looking away.
2. Immediately grab his body and dump it in the bathroom, then holster your pistol.
3. Head down the corridor the guard was covering, then kill the next guard when his back is to you. As long as he doesn't run into the next corridor, he won't alarm anyone, even if he shoots.
4. Once he's dead, just walk down the ramp in the hallway and walk to the room down the corridor to your right. Make sure the elite guard isn't down this corridor before you walk down it.
5. After you enter the room and get your envirosuit back, the trophy will unlock.

The following video demonstrates both Nothing to See Here and this trophy immediately after. I do it on Impossible difficulty, so the path I take will work on any difficulty.
