Microsoft has announced that UNO Rush will be released on Xbox Live Arcade tomorrow, 25th March, for 800 Microsoft Points (GBP 6.80 / EUR 9.60).
It may look much the same as UNO, which is already out on XBLA, but Rush is a faster variation where you shuffle your cards between goes, and then when your turn comes around the game automatically plays every card off the top of your pile that makes a playable chain.
During this time, others can observe your hand and plan their moves accordingly.
On top of that, UNO Rush has full Avatar support, works with the Scene It? "big button controller", and allows for four players locally and up to three guests when playing over Live - i.e. four people on one console over the internet.
All of which sets it a bit apart from UNO, or at least more than anticipated. As usual, you will be given a demo version to help make your mind up, and 200 gamerpoints' worth of juicy Achievements to try and tempt you into a purchase.
