Poor game IMHO. The guns are rubbish (and the targetting system was awful). Initially you think you can run anywhere but you can't as soon as you want to investigate you get the 'radiation' warning - commenly known as you can't go there. When I originally played it, it was unfinished rubbish. Now it's just rubbish. The sequel is no better either (for lots of reasons I could go into). You can get it in most second hand games shops for £1. M.
