Welcome to FriendOS, a singleplayer/online bullet-hell RPG set within a virus-infected computer. Join other Friends to face difficult challenges in a forgotten virtual world.

Rally Against Viruses

Perform in novel, acrobatic combat and beat down Viruses in a chaotic, metaphysical baseball arena. You can rally projectiles with other Friends to rapidly build damage, turning baseballs into weapons of mass destruction.

Virus combat is designed to be simple and approachable – but the difficulty can be pushed up as far as you’d like to boost your rewards. Will you let your Hubris be your downfall?
