Join the IMP! A forgotten caste of warriors that rise once more to destroy the alien plague that disrupts the Imperial Refineries across the system!
IMP mixes the simplicity of arcade games and the cinematic look of modern titles to bring you the evergreen experience of being a lone space marine fighting hordes of aliens. You will be dropped straight into the fight in levels that change every time you load in.
You are the first wave. Your armor is old. Your guns are old. You have no support in the field. None of the fancy gear of the glory days exists anymore. You don't even know if the mission can be accomplished. The citizens of the empire see you as nothing more than a glorified exterminator...
But this doesn't dissuade you! They do not know that for the IMP, the battle is sacred!
Before the alien plague, the warrior caste of the Orkarian Empire withered in poverty and menial jobs as peace had prevailed for centuries. Now they can join the Imperial Marine Patrol and single-handedly take on entire swarms of alien bugs, saving their Empire millions, and allowing them to bask in the glory of profit!
The Orkarian Empire in its benevolence allows these once proud warriors to engage in their craft once more, but not without risk. If you fail, the mission cost will still be deducted from your salary. No one said making a profit was easy!
The IMP work alone to maximize profit, doing their job in the desolate moons and planets that populate the outskirts of the system. It is here that the Empire extracts precious resources without any regard to the ecosystems.
IMP embraces the offline, single player experience that ruled the video game design landscape of the 80's and 90's. Press start, begin shooting! No sign-in screens, no premium currency ads, no filler!
This is but the beginning for IMP! Join a lone developer in early access to see how this game shapes up over the course of 2 years. Supporters are encouraged to submit their feedback and join the community to make this game grow!
