Promethium key free

The Promethium armada is headed to Earth, leaving a toxic trail of destruction in its wake. Commander Braybrook, it is your mission to take up the experimental deep space fighter and stop the armada before it reaches us - YOU ARE OUR ONLY HOPE!


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 youre after a nice calm casual game, this isnt it!

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!


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. Every time you collect a power pod the next power-up becomes available to you. Some power-ups are single use, some are multiple and some are timed. Experiment to find your perfect combination.


Promethium can be played on a joypad or if youre really brave and have the reflexes of a Ninja Cat then you can use a keyboard. Id really recommend a Joypad though, this game is tough enough as it is.

Use any analog stick or the d-pad to control the experimental fighter, or in keyboard mode use WSAD or cursor keys to fly.

You can fire using any of the triggers, bumpers or the B button on Xbox 360 or Xbox One controllers and the O button on the Dualshock controller. If you are in keyboard mode you can press the space bar to fire.

You can buy the current power-up by pressing the A button on Xbox 360 or Xbox One controllers and the X button on the Dualshock controller. If you are playing using a keyboard then any key other than WSAD, Space or the cursor keys will allow you to buy the current power-up - Id suggest the return key is a handy one.
