Medal Hunt

Cracking MCC's 280-medal pool, one fire at a time

Halo MCC tracks ~280 different multiplayer medals across all six games — way more than original Halo 3's ~60. Every game we play uploads the full medal payload from the carnage XML, but we only know the names of some of the IDs. This page aggregates every medal slot ID we've seen and shows what we know vs what's still unidentified. As we play more, the unknowns sort themselves to the top and patterns emerge.
