Total Borderlands newbie here that just bought the game during BF. I'm only an hour in but what is all the crap that I'm collecting in the chests? I understand when I'm picking up a weapon or a health pack since it tells you what the item is when you hover the cursor over it. But there is a ton of crap that doesn't provide any details on what I'm picking up. I just hold down X to vacuum it all up and before I know it, my inventory is full. But I have all these empty weapons slots. Is it ammo? How do I know what I'm picking up?
