A far cry from leather and swords, you'll be playing an engineer who can sacrifice parts of his humanity for cybernetic upgrades. How much humanity you're willing to give up seems to be one of the game's central struggles, with NPCs reacting to you differently depending on how human you are.
You're on one of the last remaining ships carrying humans after an attack on Earth and, as you have probably have already guessed, you'll be attempting to save the human race from being eradicated. Also mentioned in the release: A co-op multiplayer mode for up to four players. More info on the game is due in PC Gamer's September issue and (we would bet) during E3.
