Worms: Open Warfare 2

"Worms: Open Warfare 2 features plenty of single-player content, new multiplayer modes like Forts mode and Race mode, and of course you can customize your teams and schemes to your heart's content. On the Nintendo DS, the game takes place on both screens, there's full support for all wireless modes, including Nintendo Wi-Fi Connection, and the included landscape and flag editors have been specifically designed for use on touchscreens. The Nintendo DS-exclusive Lab mode features three types of experiments: Blow, Blast and Draw. In Blow, you must guide a worm to the exit with parachutes by controlling the airflow in the level. Blast lets you create on-screen explosions to blast your worm to the exit, and Draw lets you draw directly on the landscape to keep a worm from being blown into the water."
