the normal CO Power, the CO Meter is drained differently depending on which power was activated. While Super CO Power will drain the CO Meter completely, the normal CO Power would leave players with some leftover charge on the CO Meter depending on how much existed before the CO Power. This allows for more strategy than Advance Wars since the player must now decide between using weaker abilities more frequently or greater abilities less frequently. Plot While the Allied Nations were still recovering from the war in Cosmo Land, the Black Hole Army had already recovered and has decided to launch a large-scale invasion on Macro Land. Along with the original Black Hole army's commanding officers (COs), four new COs were recruited, under the command of Sturm: Flak, Black Hole's strongman in charge of invading Orange Star; Lash, a girl genius having invented most of Black Hole's technologies, invading Blue Moon; Adder, a narcissic commander in charge of invading Yellow Comet; and Hawke, Black Hole's second-in-command and Sturm's most trusted ally. Sturm orders each Black Hole CO to invade and capture each of the four continents controlled by the four other armies from the original game: Orange Star was to be taken by Flak, Blue Moon by Lash, Yellow Comet by Adder, and Green Earth by Hawke. Lash also invented several new war weapons like the Black Cannon and the Mini Cannons that were to be put to use in this invasion. The four allied armies must now work together to drive Black Hole out of their world once and for all. Once the Black Hole troops are driven from the Allied Nations' continents, their COs convene in Black Hole territory, near Black Hole's base of operations. Here they fight Sturm, the mastermind behind the invasion. The final battle takes place in front of the Death Ray, a powerful new weapon guarding the entrance to a missile, which, if not subdued in time, would destroy half of Wars World. The Death Ray is eventually destroyed by the COs of the Allied Nations, who manage to disarm the missile and corner Sturm. In an act of desperation, Sturm attempts to blow up the base and inflict damage on Wars World by self-destructing the missile. Andy attempts to stop Sturm to no avail. However, in a surprising turn of events, Hawke, second in command to Sturm, betrays his leader by killing him
