The classic arcade hits just keep coming to Xbox Live. This week Xbox 360 owners will be treated to the original arcade version of Contra. You'll play as Bill Rizer or Lance Bean, two unfortunately-named alien-stomping tough guys. Contra will cost 400 Microsoft Points. It includes eight levels which can be played single-player or co-op, either on the same Xbox or on Xbox Live. There will also be a special enhanced mode with improved sounds and graphics, such as rendered bullet effects and explosions. The game includes 12 achievements and leaderboard rankings. Contra will be ready for download this Wednesday.
