UFO Motherships

UFOs and a UFO Mothership.

Motherships have the appearance of a giant UFO. When every UFO in the level is dead, each mothership ascends 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.

No Enemy can move onto a tile which a UFO Mothership is on.
