An updated version of the original Vermin Invaders game. Unlike the original downloadable Vermin Invaders, which used a password system to let you pick up where you left off, Vermin Invaders DX automatically saves your progress. This allows you to access parts of the game that you've already completed without memorizing passwords. That's only the tip of the iceberg, though. An all-new Expert Mode has been added, some graphics and musics have been updated, a better ending has been added, some bugs have been fixed, and a new secret has been thrown in.
