MW4 and Warzone Season 1 adds four new weapons. Two are free battle-pass unlocks at launch: the Cronen Osprey assault rifle (882 RPM, 30-round mag, tier 16) and the CSG-35 SMG (1,200 RPM, 28-round mag, tier 36). Two more arrive later in the season through events: the JAK 12 shotgun and the ZLR Talonhawk melee axe. Crucially, both launch guns are free base weapons — no premium pass required.
Here is every Season 1 weapon: the stats that are published, how each one unlocks, and which to prioritise. Figures are from Activision’s battle pass reveal and launch coverage (GameSpot, Dexerto, mypandaplay), as of 2 November 2026; Season 1 launches 6 November and the event weapons’ full stats were still pre-release at the time of writing.

How to unlock each one
The four weapons split into two routes. The Cronen Osprey and CSG-35 come from the battle pass: reach tier 16 for the Osprey and tier 36 for the CSG-35, and because both are free base weapons you unlock them whether or not you own the premium pass — you only need to earn the tiers through normal play. Blueprint variants of both sit deeper in the pass (tier 73 for the CSG-35, tier 87 for the Osprey) and do require premium. The JAK 12 shotgun and ZLR Talonhawk axe come from in-season events that go live after launch, so you’ll complete a set of event challenges to earn them rather than climbing the pass. If you want all four, plan to grind the pass to tier 36 first, then tackle the weapon events as they rotate in through the season.
Which to chase first
Prioritise by playstyle and effort. If you play objective or medium-range multiplayer, grind to tier 16 for the Cronen Osprey first — an all-round 882-RPM AR is the most broadly useful day-one unlock and only needs 16 tiers. If you’re an aggressive, close-range player, push on to tier 36 for the CSG-35; that 1,200-RPM fire rate is the standout close-quarters tool of the launch pair. Both are free, so there’s no cost decision — only a time one, and 36 tiers is very achievable in the first week or two with the double-XP tokens the pass hands out. Leave the JAK 12 and ZLR Talonhawk until their events arrive; they’re situational (a shotgun and a melee weapon) rather than core loadout pieces, so there’s no rush. We’ll add exact event dates and the event weapons’ stats once Activision details them.

Stats are as of 2 November 2026, from Activision’s Season 1 battle pass reveal and launch coverage (GameSpot, Dexerto, mypandaplay). The JAK 12 and ZLR Talonhawk were pre-release, so full stats and event dates were unconfirmed; we update as they go live.
