Abbex came into the market back in October of last year with two Spectrum games progams. We are yet (April) to see anything new from them which seems to suggest that the original games are of exceptional quality. Of the two, Spookyman and Cosmos, the only one that really caught my eye was Cosmos (surely the world has seen enough Pac-man copies by now!).
The scenario of the game is as follows: you are in charge of a fleet of ships which must be protected from successive waves of aliens and from meteorites which just happen to come along. Each time either a meteorite or an alien hits a ship in the fleet it is destroyed. If you manage to destroy the total population of aliens within a quadrant of the fleet then another wave will appear in greater numbers, and the fleet will be regenerated.
Graphically the game is very good and highly addictive. The only niggles that I have are that I would have liked different space ships for each wave and secondly, your movements around the quadrant could be smoother. Even taking these into account, it is a very well-assembled game, which is just different enough to interest someone who has already seen many other space games and become addicted. Recommended.
