Armor Mayhem is a side-scrolling shooter game developed by Louissi. It features a full-fledged campaign, which is played both to progress through the story and earn money which is used to purchase new weapons and armor from the armory.

When Earth is depleted of energy and resources, huge companies set out on an expeditionary venture together to find a new source of energy for the human race. After years of searching they finally find a crystalline source of infinite energy on a far-away planet. Instantly corrupted by its power, they turn on one another. And so begins the company-company war that the series revolves around.
