Steam Store description

The Promethium armada is headed to Earth, leaving a toxic trail of destruction in its wake.

INSPIRED BY C64 AND ARCADE CLASSICS Inspired by classic Commodore 64 and arcade games, Promethium is a hard-as-nails retro inspired side-scrolling shoot-em-up that takes place over numerous levels that get harder and harder. If you’re after a nice calm casual game, this isn’t it! Gameplay Fly left and right over the Promethium armada ships. They have shield generators protecting them. Hover over a shield generator to hack and disable it. Once all the shield generators are disabled a self destruct code will be sent to the armada ship causing it to explode. Be careful though, the armada ships are guarded by a fleet of fighters! Power-ups Destroy enemy ships and collect the power pods they drop. These power pods are like cash, they allow you to buy power-ups. The available power-ups are displayed at the bottom of the screen. The power-up you can buy is highlighted in orange.
