Back Mounted Equipment and more storage options

[Tom Clancy's Gay Ghost]

• Metal foam gun
  

You can actually make one of these out of a flamethrower.

Just use normal metal foam mix, but cooled down so that the water turns to ice and is then turned back when it heats up from the igniter.

You can, but a lot of people won't know that and having to actually build it is a pain! Engineers need more fun tools.
