And it was their stupidity that led Dregen Yor, the corrupted Kabr, and Toland the mad to join up and help the dark side defend the Death Star against the reaper invasion! But master chief comes in and has a 3 on 1 fight against them so that he could detonate the Death Star. After that, he has to beat the traveler that is at the core of the Death Star. He beats it, escapes, destroys the traveler/Death Star, the empire's fleet, and most of the reapers. And that's only level 7 of Half Life 3!
