Skip it if you…

  • Players seeking a low-pressure experience; the game is presented as tough and its levels become harder.

Our take on Promethium

Rather than relying only on shooting through enemy formations, Promethium makes disabling shield generators the route to destroying armada ships. The side-scrolling shooter structure is therefore built around flying over targets to hack them while enemy fighters guard the ships.

What is Promethium?

Promethium is a retro-inspired side-scrolling shoot-'em-up set across numerous levels that become progressively harder.

The player pilots an experimental fighter against an armada heading for Earth. Each armada ship is protected by shield generators. Flying over a generator allows it to be hacked and disabled; once every generator is disabled, a self-destruct code causes the ship to explode. Enemy fighters guard the armada ships. Destroyed enemies can drop power pods, which function as currency for buying power-ups. The available power-up changes as pods are collected, and choices can be single-use, multiple-use, or timed. The game supports a joypad or keyboard, with controls for movement, firing, and purchasing the current power-up.
