For the first time in the history of Xbox Live, players will be able to play the online demo as much as they like, as well as maintaining all character data gathered whilst playing.

The demo will be on the cover disc of the September issue of the Official Xbox Magazine, and features "The Harbor" map in "Retrieval" mode, with up to 12 players able to take part on Xbox Live (16 in the final game). The demo will also include the Persistent Elite Creation (P.E.C) Mode which gives players the chance to create a custom player who can be upgraded. Operative classes to base your player on are Commando, Engineer, Spec Op and Combat Medic

Tom Clancy's Rainbow Six Lockdown is to ship worldwide on September 9th for Xbox, PS2 and GameCube.
