Also, do not even think about going near the Cyberdemon: its stomp will crush the player instantly. However, do not get too close to the ledges as the blasts from the rockets can knock the player into the Hell Hole to their death. The Cyberdemon's rockets are fast, powerful, and long ranged, but fortunately the rocky spires around the Hell Hole prevent the Cyberdemon from getting a clear shot at the player. The player's stamina does not decrease near the Hell Hole, so take advantage of this and use sprint constantly. Do not stay for too long in one place for any reason or the Cyberdemon will nail the player with its rockets. The basic strategy for taking down the Cyberdemon is to always be on the move. Fortunately, there are plenty of lesser demons on the level that can be killed to charge the Soul Cube. It takes 4 shots from the Soul Cube to kill the Cyberdemon.

The Soul Cube states that only it can kill 'Hell's mightiest warrior' referring to the Cyberdemon. Unlike its original counterpart, it cannot be hurt with conventional firepower instead, the player has to utilize the most powerful weapon in Doom 3, the Soul Cube, to kill it. Unlike the original version, it now has a melee attack as well: the monster can stomp on the player, killing them instantly. Like its original counterpart, the Cyberdemon attacks by firing a salvo of 3 consecutive rockets from its arm-mounted rocket launcher. Another noticeable difference is that its rocket launcher is now located on the right arm instead of the left one. This incarnation has a long tail, extending from the machinery on its back, and both legs are mechanical - as opposed to its original version, whose only mechanical leg was the right one. While the Cyberdemon overall retains its appearance as a minotaur-like giant, there are some differences of this new incarnation of the monster compared to its classic counterpart. It stands roughly 20 feet tall, more than 3 times as tall as a human soldier.
