 * Synopsis: The story starts with the space marine from Doom. The Episode 0 centers just on him and his companions, and it's 100% Doom. From Episode 1 onwards, Doom is abducted by the Vadrigar, and has to pass a series of challenges, including combats hand-to-hand with several of the characters from the game, in order to be free. Meanwhile, he gets several allies in the forms of many of the Quake warriors.
