Hordes of adorable animals and toys have gone rogue and want you dead. Boomsday is a fast-paced top-down horde survival shooter. Mow down endless swarms, loot powerful weapons, stack game-breaking perks, and survive massive bosses every 10 waves. Solo or up to 8-player cross-play co-op & couch.
Boomsday is a chaotic top-down horde survival shooter where the cutest things in the world are trying to kill you. Hundreds of rampaging cows, teddy bears, dinosaurs, and trigger-happy grandpas swarm you from every direction. Blast them into pieces, grab the weapons they drop, and stack insane perks until you're an unstoppable force of destruction. Then bosses arrive and humble you.
The game looks like a morning toy commercial. It plays like a blood-soaked arcade nightmare. Expect gore and dismemberment, this is definitely not for toddlers.
The Enemies:
There are 54 unique enemy types that will keep you on your toes. Spitters attack from range, chargers barrel straight at you, giant enemies explode into swarms of smaller ones, and Grandpa drifts around in a wheelchair wielding a shotgun. One cow even runs at you strapped with dynamite.
Every 10 waves, a boss appears. There are 12 unique bosses, each with their own deadly mechanics. One literally eats your bullets and grows bigger the more you shoot it. No matter how broken your build is, these bosses will remind you that you're not as invincible as you thought.
Weapons & Perks:
You start with a basic pistol. Everything else is earned on the battlefield. Carry up to three weapons at once and swap instantly from classic shotguns and SMGs to devastating railguns, flamethrowers, cryo cannons, and a plague gun (17 total).
Perks are chosen mid-fight while the horde keeps coming. With 36 different perks, you can go for reliable upgrades like increased damage and faster reloads, or completely break the game with orbiting blades, attack drones, lifesteal, explosive rounds, and more. Stacking them is where the real fun begins.
Co-op Mayhem:
Play solo or team up with up to 8 players. Enjoy local couch co-op, LAN games, or online play via Steam invites. Full cross-play support means Windows, Mac, Linux, Android, and iPhone players can all join the same match.
Revive downed teammates by standing next to them. The host controls the chaos in the lobby: enemy spawn rates (25%–300%), drop rates, shared XP, per-player loot, friendly fire, and more. Every run is fully seeded, share a seed with friends and experience the exact same world.
