Two games on one tape here. The first, Planet Zacron, is a straightforward bitblaster with a horizontal scrolling display.

The aliens enter from the right and move in fixed paths across the screen. Your ship can move up, down, left, and right. The opposition is accompanied by numerous asteroids which cannot be destroyed. You start off with four lives, and bonus lives seem to be added at fairly frequent intervals.

The sound is good enough but the graphics verge on the criminal. The meteorites flicker terribly, explosions are reflected in other areas of the screen, and one alien even got stuck at the edge of the display and couldn't leave the game. Under the circumstances, I felt very sorry for it.

You can only fire straight ahead, so tactical play is limited to plonking your ship in the alien's flight path and pressing the fire button. Since each alien fires once only, you can soon start high scoring with little fear of retribution. Just before you run out of fuel, you get the chance to refill your tanks by collecting pods as they rush towards you. It pays to be fairly nippy otherwise the aliens get them first. During play you face a number of different opponents, but all adopt similar tactics and none are particularly exciting to look at.

On the other side of the tape is a game called Planet Plakton. It's a feeble version of Missile Command with the poorest of graphics.

Two games for the price of one sounds like a bargain, but in this case it isn't.
