GarageGames announced they are developing Marble Blast Ultra for Xbox 360 - the game is scheduled to be available via download on Xbox Live Arcade around the launch of Xbox 360. Marble Blast Ultra is an online multiplayer arcade action game which will feature a futuristic 'astrolab' arena suspended high in the clouds where players compete against each other by navigating their marbles through moving platforms and dangerous hazards, while collecting rare gems and power-up enhancements, in an effort to complete each course in record time. There will be a multiplayer mode where players are racing to collect gems.
