Resident Evil 2 Remake: All Weapon Upgrade Locations | Gun Parts Guide

Every one of your primary weapons in Resident Evil 2 Remake can be upgraded. Shotguns get longer range, pistols become mini-SMGs, and simple revolvers become all-powerful magnums. If you search the city carefully, you can really make your basic weapons into tools of zombie destruction. To help you on your quest and fully upgrade every weapon in the game, we’ve put together a list showcasing all the locations you’ll need.

And these upgrades are very, very easy to miss. Most of them are stored in locked safes, behind optional puzzles, or hidden in secret locations that can only be discovered with film rolls. Getting the upgraded weapons in RE2 can be difficult — especially the SMG for Claire or the Magnum for Leon. If you don’t want to miss anything, just keep scrolling down. Some of these upgrades are actually really cool, and completely change the functionality of your weaponry.
