yea u have to down someone by the box then revive them and pick up the gun at the same time... its complicated

wo1f wrote sorry to tell u this but there is only one extremely hard way i saw of. when someoone reloaded their gun he got downed while reloading and he had no wep and just used the box to get a 3rd one. ive heard of this not seen it or confirmed it, it could work, but its EXTREMELY hard.

i've done this twice today, once on accident. it doesnt always work, but just try a couple times.
