    About the game

    Atomic Picnic is a Co-Op Shooter Roguelite based on the new Swarm Survivors genre! Get together with up to 4 friends to fight frenzied monsters and gain experience to upgrade your weapons in an anime-style post-apocalyptic world. Fight your way together through The Zone, an everchanging labyrinth created after the "Harvest Festival" happened. Unlock an incredible variety of upgrades that can radically change the way you play every time.
