Rank (Halo: Reach)

The Ranking System in Halo: Reach is based on Credits (cR) earned through Forge, Multiplayer, Campaign and Firefight matches. Players earn Credits after every game and they can earn extra Credits for medals earned during that game such as Double Kills, victory bonuses, Commendations and Daily/Weekly challenges.

Credits earned towards a player's rank can be used to purchase various armor permutations from The Armory. Players can view additional armor that they can't yet purchase at their current rank. Any Credits spent on armory purchases do not decrease a player's rank.

Playing Halo: Reach offline is the easiest way for players to earn Credits in either Custom Games or in Forge mode. Although once an account has been connected to Xbox LIVE then any credits earned in any mode is significantly reduced than those awarded for playing online multiplayer via Xbox Live or in the Campaign.

An account that has not been connected to Xbox LIVE but has earned credits and ranks from offline modes will lose both several ranks and a large amount of credits after being connected for the first time.

Trivia

 * The Haunted Helmet is available to Bungie employees at any rank but players can only obtain it once they have reach the rank of Inheritor and purchase all Helmet Items found in the Armory.
 * The ranks after Lt. Colonel Grade 3 were unlocked on November 2, 2010 after the Halo Reach community completed a total of 117 million Daily and Weekly challenges.
 * The Rank "Commander Grade 3" Icon is glitched, showing up on bungie.net as having two bars under it, but in the game, it is without those bars.
