Halo: Reach isn't even out in stores, but IGN has already found a way to exploit part of the game for the sake of easy Achievements. In this video, its outlines a surefire method for farming up a good amount of the game's cheevos by tweaking the customized Firefight system to be really hard and then giving yourself invincibility. Which means "you can basically shoot around in circles, and get massive amounts of points." Seems like fun ... we guess?
If nothing else, this shows off just how customizable the multiplayer system in Reach actually is. Bungie has made it so that the priority is coming up with fun gametypes with your friends, not just tweaking for as many points towards Achievement as possible. Not that we don't appreciate sweet, sweet cheevos, but that's not the only reason we're Firefighting against the Covenant, right? Right?
