Weapon upgrades | Weapons in BioShock Infinite BioShock Infinite guide, walkthrough
Last update: 13 February 2020
You can upgrade weapons in BioShock Infinite. However, it isn't possible whenever you want. On this page, you will learn when you can upgrade weapons. You will also find a list and prices of all available upgrades. This should make it easier to plan buying weapon upgrades.
Every weapon available in the game (aside from the Crank Gun) has four upgrades. You can upgrade the weapons using the Minuteman's Armory machines scattered throughout the entire Columbia. You will be finding these vending machines often so you shouldn't have any problems performing the upgrades, assuming of course you'll have enough money.
Each upgrade has its price - it can cost from 200 to even more than 700 dollars. This means that you won't be able to immediately upgrade each weapon you find. You must choose weapon that you use most frequently and upgrades that increase effectiveness and usefulness of a weapon the most. You should thoroughly explore all locations and perform other actions that will enable you to obtain silver eagles.
The table seen below offers a complete list of possible upgrades along with the costs of attaching them to your weapons.
