Targ

The Crystal City has been overrun by Targ Riders and it's up to you to drive around the 9x9 grid and shoot them all, over various levels in your Wummel vehicle. The game is viewed from above with the whole grid shown on the screen. You must drive between the squares that make up the grid and fire your missiles and when all Targ Riders are destroyed you move on to the next level. If a Targ Rider touches you then you lose one of three lives.
