Breeder Protocol

Drop into a living alien hive with up to three friends. Reach the stranded crew before the Breeders do, bring the colony uplinks online and fight your way to extraction. A twin-stick co-op roguelite where every hive is new and every run builds a deadlier squad.

About the game

The colony went silent. Something is breeding in the dark. Breeder Protocol is a 1–4 player twin-stick co-op extraction roguelite. Your squad drops into a procedurally grown alien hive, races to reach the stranded crew before the Breeders get to them, brings the colony uplinks back online and fights its way out, if it can.

Twelve operators, veteran marines and battle-tested androids, each have their own voice, personality and signature ability: call down a Rally Cry, hijack an enemy drone, ring yourself in napalm or perform field surgery under fire. Bots fill any empty slot, so the squad is always four strong.

Key features

  • 1–4 player online co-op with drop-in bots and built-in squad voice chat; local co-op with controllers
  • Procedurally generated hives: tunnels, egg nurseries, flesh pits and colony ruins, never the same drop twice
  • 12 voiced operators with signature abilities
  • Five weapon classes (Pulse Rifle, Breach Scattergun, Smartgun, Incinerator, Arc Caster) with heat management instead of reloads
  • Field Upgrades that stack into a build mid-run, plus call-ins like sentry drones and orbital supply pods
  • Campaign, Daily and Weekly challenges, endless Swarm mode, community Contracts and Ironman
  • Full controller support, built for Steam Deck
