Power to the People!

Another big difference in BioShock 2 is the ability to apply up to three upgrades to each weapon (Hack Tool and Research Camera excluded). Unfortunately, there aren’t enough Power to the People machines to fully upgrade every weapon in the same playthrough, so therefore you must pick and choose. As far as unlocking these bonuses is concerned, you just need to find every Power to the People machine (see the maps in the walkthrough for specifics) and make sure to apply all three upgrades to at least one weapon.

Icon	Title	Points	Trophy	Description
	Upgraded a Weapon	10	Bronze	Upgraded a weapon at a Power to the People Station. You’ll unlock this bonus as soon as you make your first selection at a Power to the People machine. And considering that you can’t possibly overlook the machine in the Security Wing of Ryan Amusements as you walk down the hall past the lockers, it seems you’ll have no trouble earning this bonus.
	Fully Upgraded a Weapon	10	Bronze	Installed the third upgrade to a weapon. One of the new features in BioShock 2 is that each weapon now has three upgrades instead of just two. There is typically only one or two Power to the People machines per area, so it’s best to focus your upgrades on the Rivet Gun early on and stick with it. Unlike in the original BioShock, the number of available upgrades far outweighs the number of vending machines, so fully upgrading your entire arsenal is impossible. Weapons must be equipped with the first two upgrades before the third becomes available. It’s possible (though not necessary) to unlock this bonus as early as Pauper’s Drop if you apply your two upgrades in Ryan Amusements to the same weapon.
	All Weapon Upgrades	20	silver	Found ever Power to the People weapon upgrade in the game. There are a total of 14 Power to the People machines in the game, and though you can’t possibly apply all three available upgrades to every one of your weapons, you can amass an incredible arsenal by using these vending machines. Regardless of this Achievement/Trophy, finding every Power to the People machine should be one of your top priorities—fully upgrading even just one or two weapons can make a huge difference in the latter portion of the game. Consult the maps and text in the walkthrough portion of this book for details on each Power to the People location. They are scattered across the many areas of Rapture as follows:
