About Supernova: The "Charon" Protocol — Gameplay Overview & Features

Supernova: The "Charon" Protocol is a vertical space shoot 'em up where the screen floods with fire and you thread your ship between hundreds of bullets. The last fleet is making its run — and you are flying point.

Fight through eleven sectors, from Earth orbit to the void rift. At the end of each one waits an enemy flagship: a multi-phase machine with turrets you can shoot off one by one and attacks of its own. It forgives one mistake. Never two.

Between sorties there is the hangar. Pick your hull and your gun, add drones, a bomb bay and a wing of escorts, paint the ship your way and fly back stronger. Every credit you earn in battle goes into the next upgrade.
