Today on Xbox LIVE Arcade, players can pick from two new releases that are available as we speak…er…type.

Warlords , available for 400 MS Points, is a multiplayer game where participants must knock other kings out of their castles while keeping their own king protected. Players use a shield to defend their fortress and launch a flaming ball to break down the other players’ forts. Up to four friends can play, and The Evo mode allows players to import their own pictures to their castles.

The second game available today is Buku Sudoku , available for 800 MS Points, the first Sudoku game for XBLA, which takes the pen-and-paper puzzler high-tech with HD graphics, helpful tutorials, single and multiplayer game modes. With over 1,200 puzzles that will give you plenty of opportunity to challenge your own brain, play cooperatively with friends, race head-to-head to see who can complete a board first.
