About This Game

PHOSPHOR is a retro cyberpunk roguelike platformer about fighting your way down through an infested industrial facility. Blast through hordes, kill giant bosses, and arm yourself from a pool of 350+ weapons and upgrades. Every descent is a brand-new world. Die, keep the cores you banked, unlock new operatives, and drop deeper.

You are a reclaimed husk sent down into the Underfab, a dead industrial deep lit only by the phosphor glow of failing machines. Each run takes you further than the last. Scavenge weapons off a facility that hasn't finished dying, learn which lights mean loot and which mean death, and put together a build that can survive one more biome. Bank what you earn. Then go again.

Multiplayer Online co-op puts your whole squad into the same descent. Split the loot, stack your elements on the same target to set off bigger reactions, and cover each other when the swarm closes in. If someone goes down, fight your way to them and get them back on their feet before the run is lost.

Nothing down there kills you without warning. Electric fences pulse on a rhythm you can time and walk through clean. Bosses wind up before they swing, change tactics between phases, and tear their arenas apart in ways you can see coming. When you die, you'll know exactly what got you, and how to keep it from happening twice.

Loot runs six rarities deep, and every weapon has its own trick: shots that pierce, chain, ricochet, charge up, steal health, execute weakened enemies, or hunt targets on their own.

• Elemental reactions. Fire, toxin, shock, and ice are dangerous alone. Land a second element on a target already carrying one and it reacts: Thermal Shatter, Superconduct, Combustion, Corrosion.

• Synergy sets. Complete a set and the way you play changes. Your attacks start igniting. Your crits execute the weakened. Your kills refresh your dash.

• Keystones. Legendary finds that bend the rules for the rest of the run: every shot chains, every shot bounces, every elemental hit procs.

• Operatives. Unlockable characters that play nothing alike, from a glass cannon to an armored brawler, a cyberspell caster, and a revenant that heals by hurting things. Each has its own kit and its own feel.

Win or die, you come back to the Foundry, the facility hub where your cores get spent. Permanently unlock new gear, tune your starting loadout, climb the forge perk tree, work through Contracts, and read the Archive as more of the story surfaces every run. Then pick how you go back down:

• Descent — drop straight into a fresh run.
  

• Custom run — pile extra hazards onto the run for bigger payouts.
  

• Daily & weekly challenges — the same seed for everyone, and your own best on it to beat.
  

• ENDLESS - Clear the Core and the descent doesn't stop — The facility loops for as long as you can keep up.

Every run is seeded. Enter the same seed twice and you get the identical world, loot and all — race a friend through it, or take another shot at the run that killed you. The way down covers 19 biomes, from the Transit Tunnels to the Core, with over a hundred enemy types and variants, 18 elite affixes, and 20 bosses that each fight differently. Between the fights you'll find:

• Shops, repair bays, and free caches to keep you kitted out.
  
  

• Boon altars — powerful gear bound to a lasting curse, with cleansers to lift it if you dare.
  
  

• Mini-events — ambushes, hold-the-line survivals, and sealed vaults that punctuate the descent with bonus loot.
