Bloons-style tower defense inside DOOM II: build marine towers, pop demons layer by layer, survive 40 rounds.
Build and upgrade marine towers from an overhead view while DOOM II's demons march down a winding tech-base track. Like layered bloons, tough demons split into weaker ones when killed: Imps drop Shotgun Guys, Barons split into Hell Knights, and the Cyberdemon boss bursts into four Barons.
Four towers (Marine Gunner, Rocket Turret, Plasma Coil, BFG Sentinel) each have two upgrade paths, from Super Shotgun to BFG 9000. Invisible Spectres need a visor, and armored Mancubi shrug off bullets. Survive 40 rounds on Nukage Run. Solo.
Everything you see and hear comes from your own DOOM II. Inspired by Bloons TD 6 (not required).
