This is especially helpful if one died at this fight before, and are stuck with a low health bar. From there, blasting him with rockets will cause the creature to drop valuable health, armor, and ammo. Hit the Cyberdemon with a blast from it, and he will be stunned. The Spider Mastermind or Spiderdemon in short or Aranea Imperatrix, is the final boss in Doom (2016), which possesses the body of Olivia Pierce in order to defeat the Doom Slayer once and for all. Subsequently, question is, who is the final boss in Doom? It is the boss in the level Lazarus Labs. Similarly, what level do you fight the Cyberdemon? The Cyberdemon is a returning enemy in Doom (2016). The Cyberdemon then swings its arm, sending Iron Guardian flying. He did decapitate me quite a few times with his sword moves but not much more than the average tough arena fight. The second half of the fight felt like a copout but it did make it a little more intense. You can attack him from here, but be careful: as the fight goes on, the Mastermind will electrify the floor, then send spikes up through the pillars to damage you. The Cyberdemon grows angry, as it tries to stomp Zeke, only to be blasted away by Lady Fire and Iron Guardian. I recently beat the game on UV on PS4 and I found the Cyberdemon to be a bit tricky. Also know, how do you beat brain Spider doom?Īs soon as you see the purple glowing mist start to form, double-jump up onto one of the pillars.
