Game: Doom (1993)

Gamers enlisted into the army of the future but no one signed up to stop Hell itself. Even more so, no one joined up to face Hell's doorman, the Cyberdemon. In all of his incarnations, this demonic warrior is big and delivers a hellish barrage of rockets along with a knowledge that you are not going to survive. The Cyberdemon roars a mean game and has the firepower to back it up, even if you enter the fight with the BFG.
