Who remembers around 10 years ago in the UK, an 'Aliens' movie themed thing toured around?

It was usually in venues concerts got held and things. You started out on a spaceship walking through and you had a 'soldier' guiding you around telling the crowd something was wrong and he had to check what it was. Then the lights cut out and one of the aliens from the movie would chase everyone about while the soldier fired shots at it and things. Does anyone remember this? I dont think it was around for long but it was really good.
