An impressive intro based around an archaelogical find in Cairo starts off this game. Once into the game proper, you realise that it's a DOOM clone running on your ST and a damned fine one too. OK so you don't get texture mapping or a choice of weapons and there's only one 'breed' of alien but it's the same basic concept. Your goal is to navigate the maze, blasting aliens as you go, and collect the three keys which open doors leading to deeper levels. To win the game you must collect all four computer disks hidden beyond those doors. Control is by joystick or keyboard and there's Map and Help features built in.
