What the developers have to say:

Why Early Access?

“Boomsday is playable and already has a lot in it, but a co-op shooter that runs across five platforms needs far more testing than I can do alone. Early Access puts real players into real matches: finding the bugs I cannot reproduce, telling me which weapons feel weak, which perks are broken in the wrong way, and where the difficulty stops being fun. I would rather fix those things with players than guess in the dark.”

Approximately how long will this game be in Early Access?

“Before the year is out. I am a solo developer but I work day and night on Boomsday, The game leaves Early Access when the remaining modes are finished, the balance feels right, and co-op has survived enough real matches that I trust it completely.”

How is the full version planned to differ from the Early Access version?

“More of what is already there, done properly. The plan in rough order: finish the three modes still in development (RPG, Two of a Kind and Dungeon Sweep), add more bosses, weapons, perks and enemy types, and keep tuning balance and performance based on what players report. I am keeping the scope honest rather than listing features one person might never deliver.”

What is the current state of the Early Access version?

“Everything in the About This Game section is in the game right now and playable today: the main Classic Mode, 40 weapons, 64 perks, 39 enemy types, 12 bosses, and co-op for up to 8 players with cross-play, local and lan support. ”

Will the game be priced differently during and after Early Access?

“Nope.”

How are you planning on involving the Community in your development process?

“Directly. There is no layer between you and the developer here: I read the Steam forums and the Discord myself, and what players report decides what I work on next. Every run in Boomsday is seeded, so if something strange happens you can send me the seed and I can replay your exact world to hunt the bug down. Balance complaints, performance reports from unusual hardware, feature ideas, all of it is useful. I am active day and night every single day.”

About This Game

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.

PLAY IT YOUR WAY:

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.

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.

The Enemies:

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.

Weapons & Perks:

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.
