A Cyberdemon is featured on the box art and the title screen of Doom II. Cyberdemons attack the player by using their arm-mounted rocket launcher with rockets identical to those fired by the player, which are shot in threes, one at a time, per attack. The rockets also have splash damage, allowing them to damage targets with missed, but close detonations. The Cyberdemon's attack is extremely powerful (even on the lower difficulty settings), and only one or two direct hits will kill even a well armored player. The Cyberdemon was originally designed as the end-of-chapter boss of the second episode of the original Doom, in level 8: "Tower of Babel", where the creature is awaiting the player in the courtyard section of the level, flanked by Lost Souls (on higher difficulties). It only makes one additional appearance in the original Doom in the secret level of the third episode, but several Cyberdemons appear in the sequels, Doom II, Ultimate Doom, and Final Doom. The Final Doom secret level "Go 2 It" contains thirteen Cyberdemons, regardless of Skill Level choice. The manual for the SNES port of Doom lists them as "Half unfeeling machine, half raging horned devil. This walking nightmare has a rocket launcher for an arm and will definately reach out and touch you. Make sure you're loaded for bear before you get to this guy." The Doom II manual lists them as "A missile-launching skyscraper with goat legs. 'Nuff said."
