Cyberdemon/Doom (2016)

The Cyberdemon is a returning enemy in Doom (2016). It is the boss of the Lazurus Labs.

Combat analysis
The Cyberdemon makes a loud demonic roar towards the Player when alerted. It has a special Rocket Launcher which can launch many smaller missiles at the Player and has the capability to charge up and shoot a massive and powerful laser. It also has an aerial bombardment weapon on its back which can be used to bomb the entire arena. It will also charge in a defensive or offensive action, either moving away from fire or dashing to the player. When in Hell, it has the ability to throw walls of fire towards the player and raise a straight corridor from it to the Player, where it will proceed to either use the aforementioned flame attack or shoot missiles at the Player.

Tactical analysis
In order to kill the Cyberdemon, its Argent Cell power core must be removed, and then (while in Hell) it must be weakened and decapitated.

The Cyberdemon has a massive amount of health, so the player must be ready for a long fight. The Cyberdemon has two stages in the fight, where with the first one, in the Lazurus Labs, it will use a random pattern of the attacks mentioned above. After being weakened, the Player can commence a glory kill where they will pull the Cyberdemon's power core out and use it to teleport into Hell. After doing so, the Cyberdemon will seemingly use Hell's energy to revive itself and fully regain health, starting stage two of the fight with a corridor attack. In this stage, the Cyberdemon will fight more aggressively, decreasing time in between attacks, finishing attacks more quickly, and adding the new Hell attacks in with the random pattern. Upon being weakened a second time, the Player can do a final glory kill in which they will stomp off one of the Cyberdemon's horns and decapitate it with it.

The Cyberdemon's array of attacks can be tricky, but are possible, to dodge. When the Cyberdemon begins to shoot missiles at the Player, they must simply keep moving away from the line of fire, same goes with its charge attack. When it starts an aerial bombardment, circles showing each missile's area of effect will show on the ground before they come down. The Player must stay out of these circles in order to avoid damage. Caution must be taken when staying out of the AOEs, however, because the Cyberdemon will continue attacking the player even before the missiles fall, especially in Hell. If the Cyberdemon begins to charge a laser, it will show a targeting line from the rocket launcher following the Player until right before it fires. The targeting line will not simply stay directly on the Player, but rather stay ahead of the direction the player is moving in an attempt to prevent the Player from dodging the attack. In order to do so, the Player must move the opposite direction right before the laser fires so that they aren't stricken. In Hell, when the Cyberdemon starts shooting walls of fire, the Player must pay attention to the level of the fire. Walls of fire near the ground can be jumped over, and walls of fire in the air can be crouched under. The same goes when stuck in a corridor, unless the Cyberdemon shoots missiles instead of the walls of fire, which then the Player will need to dodge in between each missile in a quick manner.

If the Player's health is low, a direct shot with the BFG will stun the Cyberdemon and any continuous shots from any other sorts of weapons will cause it to constantly drop health vials which can be picked up to restore the Player's health. Siphon Grenades are also useful. If the Player's ammunition is low, they should switch to another weapon and keep firing, as the Cyberdemon will occasionally drop ammo packs as it is damaged.
