IGN has given us a nice hands on review of this upcoming DS game. Here is an excerpt of this aricle…

The missions are all objective based. Some of them are simple, “kill all enemies” missions, while others require the killing of a particular leader, or the capture of certain points. Players command squads of six customizable soldiers through three different terrain types, industrial, desert and ice. We played through a few of the missions, mostly Industrial based, as well as some Desert ones. The game starts off simple, guiding newer players into the experience. We blasted through the level, killing everyone in our path, as per the objective. Enemies used cover and run-and-gun tactics, and seemed to know what they were doing. They didn’t just wait for us to cap them. The enemies did seem a lot weaker than the players however, at least early on, so the actual strategy elements didn’t fully come into play. A quick play through the multiplayer changed that perception. In multiplayer the teams are evenly matched, and the rounds are timed, making the game become extremely strategy based.
