I was bored and decided to try and survive with only the stuff i find on the ground, i take a jumper, armor, and boots to avoid getting arrested, and as a bonus I take a mini medic kit for the skill boost/sensor hud, so i dont accidentally loot a crit/defibabble marine. I take light armor, and dont take a boot knife.
The idea here is to scavenge what you can to make a viable loadout, go into the fight, and if you survive getting your ass blasted, drop your loadout and go back in to scavenge another one. For the sake of a challenge, no looting ammo/mag boxes or anything at the fobs, but anything other than that (including looting perma dead marines or colonists) is game if it's on the colony
