Marble Blast receives Marble Fu expansion
For a moderately hefty 200 Microsoft points, you can download the new "Marble Fu" Marble Blast Ultra downloadable content. The new package-o-content includes five fresh multiplayer maps and brings one new "Map Pack Dominator" achievement worth 20 additional Gamerscore.
We're not sure how much value there is in a 200 Microsoft points expansion seeing the game now retails for 400 points, but we're sure hardcore Marble Blasters will download no questions asked.
