If you die, you lose everything you took on the mission.
If you survive, you keep everything you looted.
No exceptions. No excuses. No mercy.
Nothing in this Endless Space is belongs to you.
Far into the future, the space itself is privatized. Corporations actively seize control of the Solar System and trying to extend their reach far beyond its boundaries. It will be up to you to uncover the truth and the unforgivable things humanity has committed in the deep, dark depths of space
Level the playing field. At any cost.
Become the boss of your own Private Military Company: carry out orders from corporations, earn reputation with your blood and sweat. Explore planetary bases, secret labs, and wreckage of spaceships to find new technologies, abilities, and other items that will help you level the playing field during operations.
Overcome, adapt and become better.
Remember that you have an advantage: clone the best employees and send them to certain death to probe the weaknesses of your opponents. There is no need to risk valuable human assets and expose your PMC to unnecessary legal risks, but nobody cares about the fate of a clones.
Unravel the mystery of Quasimorphosis.
A strange disease is spreading on space stations. Crew members are getting sick with an unknown fever, and the rifts are opening the way to demons from Bramphatur to our dimension. Find out the dark secret behind this threat to all life and pile up the bodies of your clones to overcome anyone standing in your way.
Don't bury yourself under crossfire.
Corporations hire ruthless mercenaries to carry out their shadow operations. Demons distort human nature and pervert human evolution. Gather a team of professionals, count your ammo, and keep track of your equipment to be prepared for any perversions of this space slaughter.
