Ghostrunner is set for the future after the global catastrophe. The city in a huge tower is the last fortress of mankind. The implant determines the membership of the various castes that divide the community. Violence and poverty led to rebellion. Players play the role of heroes and can fight in the physical world and cyberspace. The goal is to ascend the tower and defeat its ruler Keymaster. The core mechanism of the game is “one hit kills”, which means that one attack is enough to kill an enemy or hero.
