Therefore, a greater number of rockets is required to kill these bosses than might be expected, and they must be direct hits. Furthermore, the cyberdemon and the spiderdemon take only direct hit damage, and are immune to all blast damage. The cyberdemon's rockets are the same as the player's rockets however as all projectiles shot by monsters, they do not damage other monsters of the same type. When destroyed, the cyberdemon's body will instantly dissolve into voluminous reddish clouds of flesh, blood and gore, leaving only his blood-soaked hooves as he explodes, he lets out a short roar that is abruptly interrupted by the sound of his body exploding. It is also the fastest moving monster in the original game (the lost soul's charge attack not withstanding), and second fastest in Doom II (after the arch-vile). It has 4000 hit points and does not receive splash damage from explosions, making it fairly difficult to kill. It attacks by firing barrages of three rockets. The manual for the PC version of Doom II describes the monster as such:Ī cyberdemon will let out a loud animalistic, bovine-like roar when it spots a player - loud enough to be heard no matter how far away it is from the player. It occurs on a large number of levels during multiplayer, however. The cyberdemon is featured on the retail box cover of Doom II, and it appears sparingly throughout the single-player game. In the Ultimate Doom expansion, it makes additional appearances on E4M2, E4M6, and E4M7. This monster first appears as a boss at the end of Doom level E2M8, and re-appears in the secret level E3M9. By far the most formidable enemy in classic Doom, and one of the most intimidating boss monsters in video game history, it is more than capable of taking out a healthy player in one hit from its arm-grafted weapon. The cyberdemon is a towering, hellish marriage of demon flesh and technology, with a gigantic muscular stature, a minotaur-like head with prominent black and gray horns, a gored humanoid torso filled with red wiring, a metallic prosthetic right leg, and a large rocket launcher mounted on its left arm.
