Elevator Action was a nifty cross between platform jumping and action shooting. Your mission is to gather intel by opening special red doors inside the building. You were under constant threat by enemy agents, who did little more than fire at you. You could shoot them, or do a flying karate kick (I think??).
Other cool things were that the elevators were actually controllable, not an easy thing to code I can assure you :), and you could also shoot out the lights, which made things more interesting.
My version is fairly basic, and doesn't include the lightbulbs or the karate kick, but otherwise, it looks and feels very faithful to the original. I particularly like the escalators, and the escape cut-scene once you gather all intel and get to the car park in the basement! :)
