A New Challenger

A New Challenger is an experience achievement in Halo: Reach. The achievement was awarded if a player completed all of the Daily Challenges in a given day. It is represented by a tick over a matchmaking kill challenge icon.[1]

Following the shutdown of Xbox 360 Halo online services on January 13, 2022, this achievement is no longer attainable.[2][3]
