Power to the People is a one time use weapon upgrade vending machine. They are scattered throughout Rapture, and each gives one upgrade to a weapon of the player's choice, after which the station cannot be used again. The first Power to the People machines were installed in 1957, created by Fontaine Futuristics. They were installed as protection for the citizens of Rapture, although they may have been built by Fontaine in a cynical and self-serving attempt to spur armed conflict between the citizens of Rapture. They were used by various combatants many times during the war and were a successful business venture for Fontaine Futuristics. they were salvaged by Maxwell to add a little punch to his contest.
the machine has two main fuctions one it can permanely upgrade a weapon making it stronger and it can restore durability.
