minus the rock background instruments, this actually sounds great. Like a positive reprise of the theme. Which is sort of the idea since it plays this version immediately after this quote:
"Rivers, we've got a reading that Skynet's trying to activate the Time Displacement Equipment. They know they're going to lose this war. You need to hurry!"
"All the while, the Terminator theme is swelling. It's not sinister like we usually know it to be, but energetic and triumphant. Tin cans fall by the dozens, Skynet is throwing everything it has at you just to watch it get vaporized by its own weaponry. The core is FINALLY shut down, and that's it. The light in the T-800's eyes fade out, and they remain frozen in their final positions. Where the story goes at the end is determined by the choices you made and how you played throughout the game.
But for this, the final combat portion of the game, it's one of the best feelings I've ever had playing a game. Period."
