Key Rising Storm 2 gameplay - Everyone on the VC can dig a punji trap which is hilarious, the snipers get tripwire grenades which are deadly in the jungle and the sappers get about a billion MD-82 "Toe poppers" to hide in tunnels.

But the real "prank" tool is the lovely Fougasse, a barrel full of explosives buried in the ground. Its funny when it kills enemies, its funny when it kills teammates, it will often do both as its extremely sensitive to bullets and grenades and has a massive radius.

this but with vietnam. i'd play the shit out of it.

Here me out: Tower defense, but it's Vietcong tunnels.

bit idea???

I'd take a regular FPS roller coaster slop where you play as the Vietnamese against US invaders, but it's hard to develop those without US Army funding
