VERY STALE LISTS: the Pro Game Guides list dates from Apr 2021 (page updated Apr 4, 2024) and GamerTweak's from Jun 2021 (page updated Sep 10, 2025); no tracker has refreshed these codes since, so they may no longer work. Specific rewards are from Pro Game Guides; GamerTweak lists only generic 'free in-game items' for all four codes. No expired codes listed by either source. Creator: Spiel Mit Mir (per GamerTweak).
