This game is REALLY addictive, both single player and multiplayer wise!
The Bad: Only one music track (Use your MP3 player if you get sick of the music), Could of used a deathmatch mode in multiplayer, kinda wish they made single player DLC
Marble Blast Ultra was one of the many game demos I played when I first got the Xbox 360. I got so into it, I decided to buy it along side Braid! The game isn't bad at all. Most of the single player levels require you to reach the finish, or grab all the gems and then reach the finish. Very basic, but really fun in the process.
The Multiplayer contains numerous maps (and you can buy more) that you battle other players for gems on. It's not overly complicated, but can be a blast when you try to figure out how to get to a set of gems before (LOL I'm punny!)!
The game isn't anything too amazing, but it is a nice arcade gem to go along with you Xbox. For $5, there is almost nothing to lose! Hopefully there will be more games like this to come!
