Doom II, Green Day demo lead XBL releases

This week's Xbox Live Marketplace update is striking a rather combative tone, spearheaded by military-minded Games on Demand entries and the Xbox Live Arcade release of Doom II.

Starting with the Games on Demand lineup, Infinity Ward's Call of Duty 4: Modern Warfare is now available in all regions except the United Kingdom and Japan for $39.99. Microsoft is also now selling Battlestations: Midway in all regions except India and Japan, with the Eidos-developed naval action, real-time tactical game available for $19.99. Rounding out Microsoft's Games on Demand releases this week is last year's Battlefield 2: Modern Combat, which is now available in Europe, Australia, and the United Kingdom. The game was already selling in North America for $19.99.

Microsoft hasn't announced a price point for Doom II, but the XBLA rerelease will feature all of the original game's levels, as well as an all-new chapter created by the development team at Nerve Software. The game will also feature online and offline multiplayer in deathmatch and co-op flavors for up to four players.

The week's other Live Arcade addition is Voodoo Dice, an 800 MSP ($10) puzzle-solving title with 60 single-player levels, 20 multiplayer levels, and four multiplayer modes. The game is developed by Exkee, creator of Colorz for WiiWare and the physic-based PC title I-Fluid.

Harmonix and MTV Games' Green Day: Rock Band demo provides a first look and hands-on opportunity for music game enthusiasts two weeks ahead of the finalized product's June 8 release. "Boulevard of Broken Dreams" and "Welcome to Paradise" are playable in the trial, which features three-part harmonies, a game mechanic first seen in last year's The Beatles: Rock Band.
