Reviewed July 27, 2026. Game identity, Pick 10, weapon leveling and the Peacekeeper's post-launch status were checked against Activision material. Current PlayStation availability and the 25-pack bundle were checked against PlayStation Store listings. Class and weapon-specific camouflage requirements were cross-checked against recorded in-game challenge wording. Base multiplayer capacities and weapon identifications were checked against a dedicated BO2 stat reference and IMFDB, with fictional or uncertain designs labeled as such. Crossbow mechanics and legacy camo access were separately checked against historical references and the current Steam Digital Deluxe listing. Setup advice and weapon comparisons are editorial and avoid unsupported damage or time-to-kill claims.
