Career Milestones are the overall measure of participation and performance across all Halo games. Milestones are reached by attaining a certain level of Halo gamerscore. When designated Halo gamerscore levels are reached, new Milestones are earned and awarded in the Career section. Every 100 Halo Gamerscore increases the player's Career Level.
