Call of Duty Season 4 arrives in Black Ops 7 and Warzone on June 4, and Activision has detailed six weapons you can earn throughout the season. Season 4 expands the weapon pool with new guns and an additional melee weapon, and they can all be earned for free. In this guide, we’ll highlight all the new Season 4 weapons in Call of Duty and how you can unlock them.

The Season 4 roadmap for Black Ops 7 and Warzone details a brand-new battle pass, more multiplayer maps, additional Zombies maps, and Fortune's Keep returns to Warzone. Another major highlight is a limited-time multiplayer mode designed as a "classic" moshpit playlist inspired by Black Ops 2's movement and gameplay, which will remove the game's omnimovement, sliding, and wall-jump abilities.

If you miss the unlock window for any weapon on this list, it will be added to the Armory section of the Black Ops 7 and Warzone menus. This will let you complete a different unlock challenge to earn the weapon. This also applies for any of the past seasonal weapons or loadout items you might’ve missed.
