The Gunfex is the final spoke in the wheel that is my Tyranid army. It makes short work of skimmers, heavy tanks, light tanks and any and all infantry, bar terminators and power armour.
This guy was a major factor in my beating Speed Freeks to a man (an Ork?) in just four turns during Recon. Except for one Trukk, the poor saps didn't even get out of their deployment zone due do the horrendous amount of incoming fire. Of course, the fact that the Venom Cannon can get penetrating hits against open-topped vehicles helped a lot!
PS: I keep missing the "G", writing Funfex instead of Gunfex. My spelling error has a point, this really is a funfex.
