Phosphor is a fast-paced sci-fi platformer roguelike where you descend into procedurally generated cyberpunk biomes, battling waves of drones, mechs, and biotech horrors. Master dynamic combat blending gunfire, melee, dashes, and cyber spells. Stack elemental effects like Burn, Freeze, Shock, and Poison to unleash powerful reactions, then take on massive, pattern-heavy bosses. Forge devastating builds from hundreds of weapons, passives, and abilities that synergize across runs. Unlock upgrades with persistence cores, tackle daily/weekly challenges, and push deeper with every attempt. A high-mobility, challenging 2D action game inspired by the intensity of Dead Cells and the emergent chaos of Noita. Currently in active development and beta testing ahead of Steam launch. Get to the core. The Phosphor still lives.
