What's the biggest change being made for Bungie's final Halo game? Some would argue that the visuals, powered by a brand new graphics engine, make the greatest impact. Sure, Halo: Reach looks better than any Halo before it -- but that's not what I was taken aback by. Others would argue the lack of Master Chief makes Reach feel different from its predecessors. Yes, the Spartan-III jumps a bit differently, but that doesn't define Reach's new emotional direction. No, the biggest game-changer is this: the Covenant don't speak English.

Before you angrily hit the "Back" button on your browser, hear me out. In the previous Halo games, the Covenant were like movie villains; they could even quip one-liners at you. Some would even squeal, comically, as they ran away from an overpowered Master Chief. However, because Halo Reach isn't a story about a triumphant victory -- rather, a tragedy against an overwhelming alien force -- Bungie was left with a challenge: how do you reinvent the Covenant -- familiar to a generation of Halo gamers -- and make them threatening again? You make them truly alien.
