Enemies will constantly spawn from the centre of the arena, avoid the Cyberdemon and kill enough monsters to use your Soul Cube on the Cyberdemon himself.
Repeat until dealt with.

The final boss is the Cyberdemon. You meet it at the very end of the of the game. It is in fact one of the easiest bosses to kill, the best thing to do is circle the volcano in the middle and kill all the Imps etc that crawl out of it until your Soul Cube charges. Once charged throw it at the Cyberdemon. Repeat this 5 times then it will die.

This is the final boss of the main game; the infamous Cyberdemon. He is actually fairly easy to beat, even on Nightmare. What you’re going to want to do is to stay as far away from him as possible and keep dodging his missiles, just like in classic Doom. Use smaller enemies to charge the Soul Cube, and then launch it at him a total of FOUR times. Four hits from the Soul Cube will kill the Cyberdemon.
