In this text-based, turn-based strategy game you command a colony of rats.  It's not easy, but as you complete the 15 missions you will eventually be able to become a trust adviser to King Rat!  (You can't become King Rat yourself in this game, but... maybe in the sequel ;))

This is essentially the full game but without a lot of the polish that will go into the full version, so there will be missing / placeholder graphics / voicing / SFX, achievements haven't been built in yet and there is no autosave (but in this test version you can access any level).
