also, you do not lose the key if you abort the mission. so you can do mercury survival a few times to 15 minutes and get a t1 exterminate key. take your time and go slow opening all the lockers and containers. if you get to the end and have found no crystals or mods worth keeping then you can just abort and try again without losing the key.

while it does take time that is pretty much everything in the game.
