Your mission is to enter the alien base and recover the Aartifact. You may not take any weapons or other objects with you but must rely on what you find there. On your wanders round the base, you will come across various aliens and traps, and you have limited power reserves.
The game employs excellent 3D graphics and involves you taking your little figure around either 20, 100 or 200 rooms to find the Aartifact, depending how long you want to play, and avoiding the deadly traps and aliens you encounter which seem to be set up randomly each time you play the game.
The program uses a very friendly style from the moment it is run. It asks for your name so that it can speak to you on a more personal level, and gives you the opportunity of swapping the usual cursor keys with a set comprising of Z, X, L and Symbol Shift, which are far more convenient to use.
There is also a help menu which is genuinely helpful while not giving anything away. You can also alter the speed during the play of the game.
The only thing I found slightly annoying was the screen display when you lose a life. This is fine for the first five times but tend to get a bit slow after that.
