Microsoft has been slowly working on promoting their XNA Creator's Studio and Community Games distribution system for some time now. Yesterday, that labor showed a little bit of fruit, as the Big M showed off footage of some of the new independent games at yesterday's press conference. Now, they've provided some details and screens of the first five titles to hit the service:

• Clean Up: An environmentally friendly, third-person action/puzzle game where you maintain your own little biosphere by eliminating pollutants and transforming them into energy.
• Word Soup: Described as a "tactical word hunt", players must connect tiled letters to form words and try to clear their screen of tiles in this puzzle game with single and multiplayer modes.
• Hot Potato Online: Another dodgeball game for a service that will already have two, this one has an explosive potato with a very short fuse.
• Colosseum: A 3D fighter with cel-shaded graphics. Very little information is available on it at this time.
• Megachile Pluto: This oddly-named title has you racing through solar systems and combining found resources to provide dying planets with the elements necessary to save them.
