I guess people just expect always expect there to be boxes lying around everywhere... Now you can perform a stealth kill from inside the box, leaving one deceased guard inside the box. Ofcourse, you'll have to leave the box behind, but you wouldn't want to cram in there with a body anyway."
A plain old box that provides concealment from guards as long as it remains stationary. After upgrading, a unique stealth kill can be performed while hidden under the box.
- Infinitely reusable as a hiding place so long as it is not lost or used to conceal a body.
- A unique stealth kill can be performed from the box, hiding the body inside.
