CQB is a pretty sick helmet in Halo 3 and Halo: Reach, it was commonly used by noobs but Bungie shunned them by creating Halo Waypoint. It was a default armour Pervutation in Halo 3 but then Bunghole decided to make it unlockable in Reach by doing the following steps: * Beat a set on firefight on Legendary without dying * Get over 9000 achievements * Download Halo waypoint * Use armour lock 1337 times * Get killed by a Moa on easy mode * Drink 2 barrels of Gruntiness without getting full, tired and pausing in one breath * Beat the Sun in a staring contest
