Characters travel in an airship to ??????

The coming of an enemy.  First, one vanguard and scout.  Then a few minions.  Then a lot of minions and a mini-boss.  Then the other world hits "scatterpoint" and the invasion is on!  Both realms are threatened and must set aside their differences and repel the invaders together.  The top scientists must work together (though they don't like it.) and detach the invader's realm from "scatterpoint".
