Yet another bunch of aliens for you to blast out of existence in this very well written arcade game.

This time, you are stuck on an alien planet in a crawler that has lost part of its power. All you can do is spin round and fire your cannon at the little crabs who have the disgusting habit of galloping up and spitting acid balls at you.

Each crab can kill with your photon cannon counts for 10 points and there is a bonus after each 15 you get.

The graphics really are excellent and the whole program responds extremely quickly to the keyboard. The crabs are rather Earthlike and don't look at all menacing but they still kill.

I did feel, though, that there could have been a bit more in the game to generate more interest. Perhaps a giant turtle which requires a lot more direct hits to kill could be added.

The only other problem that I found was that the game starts running without a pause on loading, so you can lose a couple of lives while you are sorting out your tape recorder.

It is a great pity that, with so many programs, when you have been killed off the computer asks you to press a key for another go, but not to end the game.

N.B.
