Waking up on Mars, the Doom Slayer is back to doing what he does best- killing demons. With a base overrun with them, players are left to defend themselves and the one survivor, Samuel Hayden. A twist of fate lands players in hell, where they continue their sole objective of taking out demons. Eventually, players will return to Mars, happy that they’ve defeated the invasion and ready for Hayden to congratulate them. What they receive instead, is more or less a kick to the curb, helping make way for Doom: Eternal.
