Alien War

30 years ago there was a tourist attraction in London called "Alien War", set in the universe of the Alien movies.  People were led through a network of tunnels underneath the Trocadero centre by Marines armed with pyrotechnic pulse rifles... and persued by Aliens!  It was terrifying! I was there - and this set of photos are from a weekend I spent with the original creators, looking to start the whole thing back up again.
