This video shows my first successful stab at the final battle with Apocalypse on Hard mode. During this run I collect all of the danger room disks, comic books, data disks, homing beacons, and Concept art found in the game. I have also viewed all of the load screen images as well as the cinematic scenes.
The final battle with Apocalypse was more of a struggle as you will see. He is at level 99 along with his four horsemen at this point in the game. Holocaust, for example, was a real pain because he seemed to have about as many hit points as apocalypse himself. I prevail with level 66 characters.
