5 iron and 1 sheet of silver and 15 cable to craft

its a defib mount but mobile, thats basically it

## Why It's Good For The Game

good for maps where there are no good spots to place wall defib mounts
or if you cant or dont want to take off your backpack (maybe using a
modsuit?) and theres no defib mount nearby
