The Extra Content Shop becomes available after completing the game. Here, you can spend Challenge Points (CP), earned by completing various in-game challenges (e.g., defeating a certain number of enemies, finding all collectibles, completing the game on higher difficulties). The shop offers a wide array of unlockables, including infinite ammo for weapons, new weapons, character models, concept art, and filters. Completing challenges adds significant replay value and allows for highly customized subsequent playthroughs.
