The player eventually becomes the Psytron - something less than human and more than a computer - and is put in charge of the Betula 5 installation. Your job is to cope with the defensive demands when the attack comes. The overall aim is to process the information (and highly detailed it is) supplied in the 20-page booklet accompanying the program.
Ian: The graphics are excellent, with instant access to the ten views around your base, all of which detail the surrounding buildings and landscapes. And a near perfect use of colour goes even further towards making the overall display startlingly clear. Each year a program comes along that sets the standard by which the others must be judged. Psytron is 1984's yardstick.
Frank: The idea is simply splendid, and there's so much going on it's impossible to get bored. With its well-defined, clear and colourful graphics, and a manageable but challenging speed, the game is addictive from the very start, and gets more so as the player progresses.
Phil: There are six levels to the game, but it'll take a great deal of practice to get there - especially as the speed is very fast. However, there's not a lot of sound used, but this goes unnoticed alongside the superb graphics. Overall, it's one of the most interesting games to come on to the market.
