Although you would think it impossible, here is yet another variant on the Invader theme. You control a laser base which moves along the bottom of the screen, and with which you endeavour to repulse waves of invaders.

The aliens move from top to bottom and generally drop bombs on you. If they reach the bottom of the screen they change into time bombs which will destroy you if you are in range.

If you complete a wave of invaders, a new lot of nastier ones appear. As usual you try to last as long as possible with your allocated (four) lives.

The quality of graphics and animation were fair but the sound effects were annoying in the extreme.

The game uses a standard two-stage load and starts with a nice detailed description of the controls and the meaning of the various items displayed during play. Other authors should take heed.
