UFO Motherships

UFOs and a UFO Mothership.

UFO Motherships are giant UFOs. When all UFOs in the level are dead, All UFO Motherships ascend from beneath the floor and generates four UFOs, one in each direction of the cardinal points, then descends back to beneath the floor.

UFO Motherships can only be killed by Spikes, Electro Tiles, Fireballs, and Powder Kegs.

Glitches

• No enemy can move onto a tile which a UFO Mothership is on.
• If a UFO Mothership is placed on a button then that button will be held down.
