In Marathon 2: Durandal, you and other survivors hunt for an ancient ally to topple the Pfhor empire.
Solo play: Marathon 2 has a popular single player campaign and updated graphics from the XBLA remake.
Marathon Infinity forces you to rewrite history to prevent the destruction of the universe.
Online play: Most multiplayer online matches are played with Infinity.
Up to 8 players can participate in multiplayer matches or co-op play. All multiplayer games are peer-to-peer and work over a LAN or, if the host is configured properly, over the Internet. You can find and chat with other players in Aleph One’s global matchmaking lobby.
If you sign up for an optional lhowon.org account, you can track your play history and compete for a spot on the monthly leaderboards.
