The landmark was passed on Saturday, February 28 and means that the game has outperformed Halo 2, which has currently racked up approximately 768 million matches played – despite being released three years ahead of its successor.
The one billionth match lasted three minutes and nineteen seconds. Using this as a basis, Bungie estimates that Halo 3 players have clocked in 63 centuries, 6,300 years or over 2 billion years on the game.
The developer’s official database also reveals more accurate figures, showing Halo 3 players have spent more than two trillion seconds or over 64,000 years in matchmaking playtime.
Halo 3 was released in September 2007 and has consistently been one of the top most played games on Xbox Live.
