About this game

Gladiator-grade carnage on a 320x200 canvas. THE COLOSSEUM is a 2.5D retro-FPS in the spirit of the nineties classics: a raycast arena in dusk light, scanlines and a pixelation shader, a wall of Roman arches and sand underfoot. Every run is three levels: clear the arena of imps and harpies, find the golden gates — and on the third floor meet the boss with his own health bar. Between fights the Langista armory is open: denarii earned by kills buy weapons that stay with you for all future runs. You carry two ranged slots plus a melee blade — switch mid-fight on 1/2/3, cycle with Q, reload with R. Come back daily for the Dungeon of the Day, collect achievements, and pick your persona: Patrician, Legionary or Gladiator — difficulty changes enemy health and damage, medkit efficiency, the ammo multiplier and spawn density. Note: the interface is Russian-only.
