Blasteria
SteamA Visual Feast Fill up the screen with hundreds of bouncing lasers, powerful charged shots, flamethrowers, lightning, droids, vortexes, and of course, tons and tons of germs.

Break The Game Find your own unique combination of upgrades to "Break the game" and create a nigh-unstoppable germ destroying machine.

Roguelike Mechanics After every wave, you'll get the option to choose one of over a dozen different upgrades and abilities. Additionally, you'll choose how the germ mutates, allowing you to manipulate the very thing you fight against.

A Science-Driven Allegory As you play through Story Mode, you'll learn the allegory of the germ through hand-drawn pixel-art portrait-style cutscenes. Beat the story mode and you'll unlock the "Endless" mode where you can infinitely stack upgrades, and attempt to "Break The Game".
