Advance Wars: Crossfire
Prologue:
After the four continents Orange Star, Blue Moon, Yellow Comet, and Green Earth defeated Black Hole in Macro Land, Black Hole rebuilt their base of operations under the command of Hawke in a continent to the north that stretched from the West Sea to the East Sea.
He called the abandoned continent Black Hole.
Five years after they rebuilt their base, Hawke sent a threat to OS, BM, YC, and GE commanding them to either surrender their continent, or die.
Accidentally the threat got sent to a fifth continent called White Nebula.
White Nebula didn't know what the threat was about, but went to war anyway.
Early in the war, Black Hole realized that White Nebula was the biggest problem, so Black Hole focused their assault on WN putting OS, BM, YC, and GE in the crossfire.
