The Next Floor

The Next Floor is a nice kind of tower defense games. It is not entirely a TD game but almost. You namely use a lift here which must be equipped with weapons that can shoot in your absence while you take care of a different floor. The whole this is more complicated when you buy additional lifts. You can drag the elevator with left mouse button to another floor, or you could let the turret do the work for you, just try everything you can to stop the waves.
