Boomsday is a chaotic isometric horde survival shooter. Blast the horde into pieces, grab the weapons they drop, and stack insane perks until you're an unstoppable force of destruction. The game looks like a morning toy commercial. It plays like a blood-soaked arcade nightmare. Expect plenty of gore and dismemberment.
Go hardcore with friendly fire and no revives. Turn bosses off. Pick your starting weapon. Share loot with your squad or keep it every-player-for-themselves. Slide enemy count, drop rates, and player health anywhere from 25% to 400%. A significant amount of effort has been invested in allowing you to play Boomsday the way YOU want to play it.
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.
There are 39 unique enemy types that will keep you on your toes. Spitters attack from range, wheelchair chargers barrel straight at you, giant enemies explode into swarms of smaller ones there is always something coming from a direction you weren't watching.
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.
Depending on your picked class 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 absurd made up weapons and more.
Perks are chosen mid-fight while the horde keeps coming. With 64 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.

New: Added two new tilesets: Steampunk and winter(Frostbound). Runs start on the original look, and every bossflip rebuilds the arena in a different tileset, picked at random. Later these tile sets will have specifical unique behaviours associated with them.All seven heroes now show battle wear: dirt on boots, dust and soot on hair and shoulders, worn cloth, and small cuts, scrapes and bruises on bare skin. Each hero's marks are fixed. During the time I was adding dirt and noise to the characters to improve their appearance (they looked spectacularly clean before) I decided to make them look like the role they play in a shooter game.New in-game HUD in every mode: a cleaner layout with thin outlines and fewer icons. Nothing blinks anymore. low health, reloading, expiring power-ups and downed teammates show as a color change.Reload indicator settings added to GAME settings , a few diffe...
Read full update on Steam ↗New Mist Environment System:Added ground mist, a layer of fog that covers the floor in every game mode. It is on by default on desktop PCs and off by default on Steam Deck, and the Ground Mist option in Graphics settings turns it on or off. Until more testing is performant it will remain as a default off setting for other devices.The mist is a live simulation. Wardens, enemies, bullets, explosions and loose objects push it aside as they move through it, its designed specifically to be performant and move with gameplay.Weapons move the mist according to their type. Muzzle blasts push it away from the barrel, bullets and missiles leave trails through it, and beams and flamethrowers burn a channels through it.Explosions, fuel barrels and grenades blow holes in the mist. The mist refills over a few seconds. Grenades type weapons leave a trail while in flight before explosion.Traps move th...
Read full update on Steam ↗This update resets the solo and co-op leaderboards and fixed runs that posted the wrong wave, kills or level; co-op squads.

All clipping from animations were removed.New look: Wolf now wears gold armor with a cape and a shield. His shield, cape and chest emblem.New Weapon: Recall Hammer - Wolf's hammer is his only weapon. Hold fire to throw it at the enemy you're aiming at. It keeps hitting that enemy until you let go, then flies back to his hand. Aim at another enemy to switch targets. Aim at empty ground and it circles there until it hits an enemy, then attacks that one. The faster it's moving, the harder it hits. Perks entirely change how his hammer operates and what it looks like.Shield: Wolf has no grenades. Hold the grenade button to raise his...

Read full update on Steam ↗This update has some balances in the wave system and are written outside the normal format due to multiple specifics:DUNGEON AND WAVE SYSTEM BALANCES:Classic and Chaos: past level 15, each level now costs 12% more XP than the one before instead of 35%, so perks keep coming much further into a run.Classic and Chaos: XP gems now scale with the wave's enemy health. An enemy with three times its base health drops twice the XP.Classic and Chaos: every player gains one full level (one perk pick) when a boss dies.Classic and Chaos: new enemy types now keep joining the fight until around minute 20 instead of all arriving in the first few minutes. The first 19 types still open the run.Classic and Chaos: after wave 30, spawn batches grow by one enemy every 12 waves (up to 14) and the enemy cap rises by 3 per wave (up to 600).Classic and Chaos: after wave 10, enemy health now rises by 2.5% of it...
