Corpse Camo - An embarrassing (but very useful) reward for dying too many times (51 or more deaths to be exact). The Corpse Camo does have its uses as it's the only way to fool unmanned weapons such as Scarabs or Gekkos.

In addition, if you hide in a box while using it, you can frighten an enemy when they pull the box off of you.
