Though the box art is extremely misleading - it doesn't look anything like that good! - this is nonetheless a very adequate implementation of the classic arcade game. You get the first space fortress, outer space, the second fortress and the Zaxxon Robot encounter, seen from the usual 45 degree angle. Get through and you go back for another, harder pass.

The differences between the 16K and 32K versions are that the former has no pause facility, doesn't have base missiles in the first fortress or altitude control in outer space, and you have to destroy the Zaxxon Robot itself, rather than its missile. Not a whole lot else to say, really... I mean, you must know more or less what to expect from Zaxxon by now, surely?
