Torchbearer is an achievement in Halo: The Master Chief Collection. It is unlocked by beating the 24,000 point par score on the level Halo. The achievement is worth 10 Gamerpoints. Though the achievement can theoretically be unlocked on any difficulty, more points are awarded in campaign scoring when playing on higher difficulties.
Torchbearer replaces the Reclaimer achievement from the original Xbox 360 version of Halo 3, one of only two campaign scoring achievements from the game which does not return in the collection. "Torchbearer" can be considered a synonym for "Reclaimer".
