Microsoft has said that Rocky & Bullwinkle and Battlezone will be your Live Arcade treats this Wednesday.
The former is based on that cartoon from the US that has a moose and a beaver doing funny things. It's been artistically reinterpreted into lots of mini-games.
Some of these work with the Live Vision Camera in an EyeToy-style way; think throwing darts or rowing an imaginary boat. There's also a hot-seat mode for you and up to 11 friends.
Rocky & Bullwinkle will cost 800 Microsoft Points (GBP 6.80 / EUR 9.60).
Battlezone is a new iteration of the vector-drawn tank-battler from 28 years ago. It looks better these days, of course, and has things like Deathmatch, Team Deathmatch and Capture the Flag.
You can use your Live Vision Camera to try and put off your friends, and even play as a flying saucer.
Battlezone will cost 400 Microsoft Points (GBP 3.40 / EUR 4.80).
