Elevator Action is a 1983 arcade game by Taito. It debuted during the Golden Age of Arcade Games.
The player assumes the role of a spy who infiltrates a building filled with elevators. He must collect secret documents from the building and traverse the 30 floors of the building using an increasingly complex series of elevators. The player is pursued by enemy agents who appear from behind closed doors. These agents must be dealt with via force or evasion. Successful completion of a level involves collecting all the secret documents and traversing the building from top to bottom. In the lower floors of the building, the elevator systems are so complex that some puzzle-solving skills are needed.
This is my first field puzzle cache, combining elevators and puzzle solving skills. All will become clear when you get here. What you seek is behind the tree to the left of the green power box. Bring your own writing utensil.
