After finishing the demo level of Advance Wars: Under Fire, controlling it seems very intuitive. It's like a combination of Pikmin and Metroid Prime.

The player controls a single unit with the analog stick. A is used to fire, B for jumping and entering vehicles. Targets can be locked onto with the L button, and R is used for a free-looking. A player can lock onto a unit and fire while running and jumping in any direction, like in Metroid Prime.

Other units can be summoned with almost the exact same system that Pikmin uses; point at a unit and hit X to get him to follow. Hold X down for a wide area of unit selection.

Units in your group are shown as a series of icons at the bottom of the screen. A single one can be selected by using the control pad and be told to move to a specific location or attack a certain enemy by pointing at it and using the Y button. The next unit in line is automatically selected, so many units can receive orders extremely quickly. Players can switch units by selecting one and hitting Z.

Like in the turn-based Advance Wars, certain units are more effective than other units, depending on the enemy unit. A fighter plane can destroy other aircraft extremely quickly, but they're difficult to hit ground troops with. Ground troops, in turn, can easily target a flying unit, but ground troops get owned by tanks' cannons.

Units need to negotiate the terrain, too. The demo level is a nice beach environment with lots of hills to hide behind. A large group of soldiers or tanks can pop up from behind a hill all at once to surprise the enemy.

During the course of the E3 demo, a commander teaches you how to play the game as you go, just like in the early levels of the turn-based games. The enemy commander drops in with his own typical-villain dialogue, too.

It's a very easy game to get into. There's no indications that commanders have certain powers or anything yet, but there's the possibility that they might have exclusive units. Only the enemy army had the really cool zepplins in the demo.

It seems very fun, but it severely needs a multiplayer mode. It seems very likely, but it's still unknown as to whether or not it will actually have multiplayer. This needs to have cool features like CO Powers or multiplayer to be really fun, so let's hope they get put in.
