Hi there, So i was browsing the internet as usual and i stumbled up the most amazing website ever. halo3.thewestwalker.net is a newly created website which is like the halo 3 matchmaking without having to click the matchmaking button! The site has the own playlists set up and you play on those playlists to gain exp and you can even enter tournaments. Also, they dont just play on normal maps, You can play on forged maps too! I hope you view the site and have a look around and mabye sign up. You'll love it.
Hmm, sounds like Halo3RPG. Or HaloCrusades. That tournament and forge thing sounds cool though *Click link*
An xbox thing. Its like matchmaking but without all of the cheaters and its a bit more fair gameplay.
