Although the player is given considerable freedom to explore the game-area the solution to the game is a linear progression through various puzzles. The main character is usually given hints on how to complete the next stage via in-game phone calls. Players are able to enter buildings (although the view remains outside the building with Sam visible through the windows - there is no cutaway), switch lights on and off, open doors and collect money (by somersaulting onto the bills blowing down the street). Sam can also don disguises for various parts of his mission and at times will also have to evade police - for example by pulling out building fuses to cut the lights at the start of the game when he finds a dead body. Sam carries a limited amount of money in dollar bills and this ticks away slowly with the game ending if Sam's money-level reaches zero.
