It's Wednesday and that can mean only one thing... there's a new Uno deck available to download. For all Uno fans that just leapt from your seat, I'm sorry. Today's new release is not a new Uno deck, but Konami's arcade classic Contra.

The game features support for two-player co-op, either online or on one console, and comes with all the usual enhancements we've come to expect from Live Arcade releases: HD visuals, leaderboards and a bunch of achievements.

The game will set you back 400 Microsoft Points, and if you're too young to remember Contra then you can download a demo to see what it's about for free.
