Halo: The Master Chief Collection (aka “MCC”) on Xbox One is currently the most popular way to play the game competitively online. Despite many of its shortcomings (countless bugs, inconsistent netcode, etc), the game offers players a quick way to jump into ranked 2v2 Team Slayer on the classic maps.
The MCC version of Halo 1 is not played at competitive events due to game-breaking issues, but it’s a great platform to learn the game and practice team strategies online.
