Demon Tower 99F

A demon king built a tower with 99 floors. You brought a Beretta, a carbine, an AK, an AWP, and a flamethrower — in that order, more or less.

Blast through arena floors of imps, brutes, and hell warlocks. Every 10th floor a Demon General blocks the stairs; floor 99 belongs to the Demon King himself. Clear a floor, step into the portal, climb. After every boss a checkpoint saves your progress, so the tower never takes you further back than it has to.

Every 5 floors you choose one of three upgrades — more health, more damage, bigger mags, faster hands, or a Dark Bargain that turns your damage into life. Enemies drop medkits and ammo; floor clears top you up. Guns don't care about magic.

Four zones rise through the tower — cold dungeon stone, molten inferno, the arcane Void, and the gilded Throne — each with its own light, fog, and soundtrack. Boss fights get their own music. You'll want the sniper for floor 99.
