The Chief is flying on the ship, then on the ground, in a firefight with Covenant forces. There is no dialog, just shooting and grenades going off. The aliens look particularly gruesome, and the artwork seems very faithful to the look of the games. Master Chief blows open a door to enter a room where he faces down a very large force... The Chief is fighting back a huge force that just keeps coming and coming. Finally, a line of enemies lines up and shoots him all at once, and he falls.
Ah, gaming: source of such rich and emotional narrative. Although in the comic's defence, it is apparently written by Brian Michael Bendis - one of the four comic writers who I could name, and who I like from reading John's copies of Powers.
