Just to let people know, I am playing with Blender to eventually put together a proper sprite/model for the HMG turret (and thumbnail for the mod itself). The ingame sprite is just currently a recolor of the vanilla gun turret, but hopefully I'll be able to make a sprite that makes use of a more robust mounting plate and houses a pair of single-barreled guns. If I can get the muzzle flashes to alternate between the barrel ends when firing, even better.

One might say it'll be like someone strapped /two/ AMRs into a gun turret ; )

I really like this mod and it is very useful when combined with Hero Turrets. Can't wait to see what sprite you come up with. Very cool man.
