Atomic Picnic

The Zone isn’t a place for loners, or at least not for long. Loadouts are loaded, gear is strapped on, and a Picnic is about to begin, with monster hordes waiting and massive bosses at the end of every run.

Atomic Picnic is a third-person bullet heaven roguelite from BitCake Studio, published by Mad Mushroom, built around explosive co-op action. Swinging, dashing, and blasting through monster swarms, combining upgrades and discovering rare evolutions, and launching off ramps and cliffs with your Impulse Gear, you’ll strategize builds, complete objectives, and take down bosses solo or with up to three friends online.

What Makes It Different?

• Play solo or team up with up to three friends in online co-op
• Use Impulse Gear to turn ramps into launchpads and cliffs into high ground
• Shoot spirals of shurikens or blaze fiery rocket trails
• Stack Cursed Curios and trigger evolutions for game-breaking builds
• Rain explosive meteor storms on enemies from above
• Complete objectives and defeat monster hordes to prepare for massive boss battles
• Follow a public roadmap as the game grows through Early Access

Fight From Above

Where most bullet heaven games keep players on flat ground, Atomic Picnic plays with verticality. The Impulse Gear transforms every arena into a high-flying playground, so ramps become launchpads, cliffs become advantages, and mini-bosses become easy pickings from above. Movement is as much a part of the build as the weapons, and swinging, dashing, and blasting around the battlefield gives the combat a rhythm that feels distinct from more static survivors-like games. It’s a lively, colorful take on the genre that leans into just how much fun it is to be airborne while the screen fills with chaos.

Harmonic Chaos

Every upgrade combo creates its own kind of mayhem. Stacking Cursed Curios and triggering rare evolutions lets players build toward some genuinely destructive setups, from spirals of shurikens to fiery rocket trails to meteor storms raining down on a horde. In co-op, those builds combine with a team’s, so coordinating who covers what, and how builds complement each other, becomes part of the fun. The developers have worked with their community throughout development, including open playtests and a roadmap players can follow, and they plan to add more characters, enemies, maps, and gameplay features before leaving Early Access.

How Long Does a Run Take?

An average main story run lasts about 2 hours total for completion, while individual session or stage lengths typically run around 15 to 30 minutes. Full solo speedruns or complete playthroughs can range from roughly 50 minutes to under an hour depending on the player’s build and pacing.

Controller Support

Atomic Picnic features Partial Controller Support for Xbox Controllers and PlayStation Controllers, and requires agreement to a third-party EULA.

Good If You Like…

If you enjoyed Crab Champions, Cowboy 3030, or Deadzone: Rogue, Atomic Picnic’s mix of third-person co-op shooting and roguelite build-crafting should be well worth a look.
