HELLSPAWN is a fast-paced retro survival-horror FPS set inside a corrupted underground bunker. Survive increasingly brutal waves of possessed creatures, unlock new rooms, buy weapons, repair barricades, upgrade your stats, and push deeper through endless Descent cycles. Every run becomes faster, harder, and more chaotic as mutated enemies, splitting slimes, flying horrors, ranged monsters, and minibosses overwhelm the bunker. Build your score, climb the global leaderboard, and see how far into Hell you can survive.
