Traverse an office building with 30 levels of increasingly complex elevator shafts
Avoid pursuit by enemy agents by using your wits or your pistol -- think ahead and know when to choose force or evasion

Collect all the missing documents, then use your puzzle-solving skills to navigate your way back through the elevators and make a clean getaway
