Warhammer 40,000: Doom Simulator

At first, I thought it was just ordinary energy fluctuations. Unexpectedly, with the accumulation of abilities. A human being who calls himself the Slayer was born! In order to resist the invasion of Doom, the four most powerful destructors joined forces and launched a desperate attack on him. But even so, it couldn't stop the invasion of the Doomsday Slayers, and the corpses of the demons piled higher and higher. In the end, the four demons could only sit on the throne and sealed the breached webway. Desperately praying that the Doom Slayer wouldn't break through the last line of defense.
