This is a short guide on how to help your friends escape from Alcatraz. There are a couple of requirements. First, you'd have to be two players, let's name them Player A and Player B.
Requirements for Player A: a screwdriver, $1 000.
Requirements for Player B: a car.
Player A: buy a screwdriver from a 24/7 store and make sure you have at least $1 000 in your pocket (in order to bribe the guard). Player B: park your car behind the Alcatraz building (in the red checkpoint) and stay in your car.
Player A should enter the Alcatraz jail, bribe the guard near the door with $1 000 and use the screwdriver to attempt to break the system. If you successfully manage to break it, the doors will open and every prison has the chance to escape before the doors are closed again. Remember that it is also possible to fail too.
