Warp Gate

Warp Gates work like Box Generators but generate a certain type of predefined enemy instead of a certain type of predefined movable object. If there is none of that type of enemy in the level at the time then the warp gate will generate four enemies of that type within itself. Warp gates feature in the Platinum Edition of Return To Wonderland.
