Upgrade Kits are the kits used to upgrade weapons in Wolfenstein II: The New Colossus for B.J. Blazkowicz, and for Joseph Stallion, Jessica Valiant, and Gerald Wilkins in The Freedom Chronicles. There are 21 kits in total during the main game for The New Colossus, and there are three for each of the Freedom Chronicles.

The upgrade kits are often being hidden in various areas in each level of the game, and can found amongst the American Territories during, or after completing the main storyline. The upgrades appear in The Freedom Chronicles, but the animation of the weapons being upgraded are shown, and also appear in cases when found.

Strategy

• When playing on Mein Leben, it's best to collect half of the upgrade kits to improve your weapons. Also, the first upgrade kit in the game should be used on the Handgun 1960 and Maschinenpistole to get the suppressor, as it's useful for the stealth sections on Mein Leben.
• It's best to get upgrades on your Sturmgewehr, Schockhammer, LaserKraftWerk/Dieselkraftwerk, Maschinenpistole, and Handgranate.
  • The Handgun 1960 and Kampfpistole can also be upgraded, but the former is based on the player's preference on using the Handgun or Maschinenpistole for stealth.

Trivia

• B.J. will state that he needs to work on upgrading your weapons if he has collected a kit, and has more unused yet. This is possibly a reminder to the player to upgrade your weapons if they forget they have one or a few.
