Mad Mushroom is excited to reveal the first title that we will publish: Atomic Picnic, a co-op roguelike shooter from BitCake Studio!  Announced during the OTK Video Game Awards today, Atomic Picnic will enter Steam Early Access in the Spring of 2024.

Can’t wait that long? You’re in luck: An open playtest for Atomic Picnic starts Monday, December 11, and will run until December 18. To apply for early access to this playtest starting today, visit right now. Starting December 11, players can join the playtest by visiting the game’s Steam page

Atomic Picnic is bullet heaven inspired third-person roguelike shooter that takes place after a mysterious cataclysm has left the world infested with monsters. Despite this, humanity continues to crave loot, fame, and glory. Now ambitious adventurers called “Loners” go on perilous scavenger hunts called “Picnics.”

Dive into adrenaline-fueled, high-octane arenas with up to four friends to fight hordes of monsters. Gain experience and upgrade your weapons and skills to create the best build possible to survive. Every Picnic is different, with a variety of upgrades that can radically change how you play.

Check out what the team has to say about this exciting title, starting with the MadMushroom CEO, Sibs: 

“We were immediately drawn to the vibrant and striking art style of Atomic Picnic. With its blend of co-op, roguelike, and bullet heaven elements, this is a perfect first title for Mad Mushroom to publish. And BitCake Studio’s commitment to open, community-first development makes them a wonderful first development partner for us as well.”

Speaking of BitCake, here’s a message from studio CEO Camilla Slotfeldt: 

“We make games to bring people together, and Atomic Picnic is a prime example of what we’re best at - creating fast, fun, ever-changing experiences that challenge friends to prevail together. Mad Mushroom’s belief in us mirrors a ‘Picnic’ in the game -- the indie landscape may be chaotic, but we’re going to have fun winning together.” 

And a video from other members of the studio!

Finally, our very own Chance “Sodapoppin” Morris had this to say: 

"Our job at Mad Mushroom is to find crazy good indie games that people will love and get eyes on them. With an audience of more than 150 million people on our streams, we have those eyes,” said Chance “Sodapoppin” Morris, Chief Games Officer at Mad Mushroom. “Atomic Picnic is a roguelike with the goods to get there, and being cooperative makes it even better. I love that shit and I hope everyone else will too."

If that’s not enough, we’re also giving away a dope Atomic Picnic PC from our friends at Starforge Systems. Head to to enter the giveaway.
