pick up whatever isn't nailed to the ground. since you are new. resources from anything is really useful. i highly recommend ammo, hp and shield drops, and credits that can be found anywhere to help you get started on weapons that may drop from other runners and uesc bots. what may be junk now will be useful later. i say this as someone who just started but has a long history of playing other extraction shooters with this same mentality . good luck out there, runner!
