Grave Robber Trophy
Collect 50 items or weapons from human corpses.As with the trophy description, simply loot from 50 human corpses and the trophy will unlock. Corpses are scattered throughout each level. To loot them, go up to the and hold down . Since you’ll probably be doing this regardless as it's a great way to stock up on items and credits, you should have no problem earning this trophy, most likely before the end of the second level.
Every so often a corpse will have nothing attainable. A corpse must contain an item for it to count towards your tally. Unfortunately, you won’t be able to tell whether one has item or not until after you search it, so you’ll have to search every human corpse you can find till you get the 50.
