About This Game

“A future in where humans lived a prosperous century and technology advancing beyond space and time,” that was what humanity should have been if not for the sudden appearance of unknown beasts of the void. A large portion of humanity were gone in the moment. War for the survival of humanity broke off all over the world, changing landscapes and settlements into warzones. Humanity were forced to relocate into shelters and reinvent their technologies into weapons of war, the M.A.S.S. technology.
