Really beautiful weapons.
the freeze mode of the A666 cannon could be a cryon weapon.
btw, we don't have any acid weapon, no?

in the game we have only a flamethrower and a poison grenade

I suggested some time ago a Freezer gun... it would be really cool to freeze people and after humiliate them killing them with some simple weapon(pistol or knife)
BTW your ideas are really awesome. the dual Thompson gun will be fun.

Yes but i visited some post with Ideas and my ideas aren't very different than ideas posted by other guy's, and it's perhaps for that reason most like the proposed weapons

I will post a lava cannon and an anti-material rifle even if it's not my idea from first i like to see this kind of weapon because it's pretty rare to see a weapon like this, the lava cannon it's an original, but perhaps someone already suggested it
