A word of warning from one of my more informed sources - floating around in zero gravity makes you sick as - nay, sicker than - a parrot. Better to adopt a more sensible attitude and go for it in the Acornsoft way.
Free Fall is as close as the likes of you and I are going to get to zero gravity, commercial space travel still waiting for its Branson-figure. The action takes place on board the deep space station Coriolis which has been attacked by Alphoids. These boys are all fun. They've injected the air supply with cyanide and only one crew member has reached his space suit in time.
It's not only Alphoids that the crewman has to contend with. The place is full of 'oids; Waspoids, Craboids, Lostoids - all do their bit towards making life very hairy.
The game simulates free-fall conditions very nicely. You can move around either by using the suit's air jet or by pushing or kicking against walls. The beasties are disposed of by kicking, punching or catching and throwing one of the bombs that float around the station. It's not easy, though. If you don't have a joystick think seriously about having a few extra hands grafted on.
