Greatest final levels (and why)

[G2ThaUNiT]

"Halo" from Halo 3 immediately comes to mind. It was an insanely intense escape after Master Chief activates the Halo ring to destroy both the Ark and the Flood infestation with arguably the greatest vehicle sequence put in a video game. Especially when playing that level with others and the cheers when you finally escape. Fantastic final level!
