The game amended some existing gameplay from the previous title, while introducing new elements, including multiplayer modes, naval units, and base structures.

The game's single-player story focuses on a new conflict emerging following the previous war that is being used to mask the search for a powerful ancient superweapon, with players taking charge of troops across three campaigns in the present, and two set at different points in the past.

Like its predecessor, the game is played from a third-person perspective, in which players take control of a variety of units that form a battalion, in order to complete missions and battles.

Qa-Len finds the staff in the blast crater, and proceeds to an icy wasteland, where she throws it into a chasm, in hopes that it may never be used again, unaware this action would spark a new conflict in the future.

Colonel Windsor and Commander Pierce, of the Anglo Isles, launch a preemptive strike on the Solar Empire, believing rumours that they are constructing a superweapon.

After returning to their nation following the conflict in the Solar Empire, General Herman takes Brigadier Betty into the Western Frontier War Room, suspecting the recent skirmishes have a familiar sense of deja vu to it, and looks for files detailing past events in the world.

By the time he finishes his story, Herman voices concern, believing he has a suspicion on who might have orchestrated the attack between the Anglo Isles and the Solar Empire.

A few days after the conflict in his homeland, A-Qira, having reorganized his forces, leads the Solar Empire into battle, and along with aid from the Tundran Territories, launches a counter-invasion against the Anglo Isles.

Nova, learning of the invasion of his homeland, launches an assault on the Xylvian forces, aided by the other nations, as he and the other COs fight to reach the icy chasm in the northern region of the Tundran Territories, in an attempt to repel Vlad's expedition for the staff.

The super-weapon causes massive destruction in the surrounding area, yet despite this, all the Alliance of Nations' CO's narrowly escape with their lives, while Vlad and Ubel are trapped in the ice, forced to dig their way out.

Sticking points included that Kuju failed to capitalize on or misused Wii's control enhancements, the inability to play through the single-player campaign in online cooperative mode, and the lack of voice chat.

[9] Official Nintendo Magazine criticised the lack of a "retreat" command and the occasionally fiddly controls, but commended the graphics and strong online mode.

[21] Hyper's Dylan Burns commended the game for its "heaps of units and high production values", but criticised it for its "iffy motion control and being a bit too cutesy".
