alo 2 Vista will also be the first PC game to have achievements which is something that every Xbox 360 game already has. People who already have a paid for Xbox Live Gold membership for their Xbox 360 will not have to pay extra for Live for Windows Gold memberships; that fee will carry over to the PC service. And what do you get when you go to the Gold side? Well while you can play online multiplayer in the PC version for the free Silver membership, the Gold membership will let players use the Quick Match and Custom Match features for matchmaking (Silver members will get access to a GameSpy-like server browser). Silver members get access to achievements in single player while Gold members get achievements in both single and multiplayer modes. Players will also be able to set up dedicated servers for free as well and there will be full voice chat support as well.
