The awesomeness that follows is a direct contribution from the badassness of Nepleslian Marines, high or not:
Chad was totally floored by the coolness that the conviently placed crater added to the butchering of before mentioned zombies. He was still fireing, (this time more out the window because everything in front of the truck was now permenantly deceased), and screaming about how 'you shouldn't mess with my roomie', and other shenanigans along that line. But the fun never ceased to stop.
Chad had never seen so much disgustingly nasty blood in guts in such quantity, and it was possibly, he decided mentally, the coolest thing he had seen in a very long time. And as they crashed through the last few zombies between the now redneck occupants, and Jack, he felt all the wieght that had previously been a buzz kill, cease to exist.
He smashed out of the truck as best he could, fireing into the remaining twenty or so zombies. When he reached Jack and Kajiim, he through the STAR he had brought at Jack's feet. "Take it," he said to the rifle's new owner, "you need it more than I do right now." And as he gave the STAR to Jack, he unslung his HPAR and let the zombie SOB's eat the molten coin round in full auto. His new strength gave him the speed he needed in the AIR2 to roll and dodge when needed, and even when it wasn't he did it anyway just to make this a more reverent memory.
As far as Chad could see, he was invincible, and nothing could screw him or his team now. All that was left was to grab the senators and get the heck off this rock.
