Scientists from the UAC United Aerospace Corporation began to study the ruins of an ancient Martian civilization, in particular, tablets describing extraterrestrial technologies. According to information from them, the Martians, conducting experiments on teleportation, discovered that the movement occurs through a certain dimension.

Destroy all demons and bosses and close the portal to hell once and for all
