MW4 Season 1 delivers four weapons on November 6. The MP5, SCAR-H, and FMG-9 are not among them.

Two weapons sit on the free Battle Pass track. Two more are locked behind in-season events. Here is exactly what to grind and what to skip.

Confirmed Season 1 Weapon Roster

Takeaway: Skip the Battle Pass if you only want the shotgun or knife. Both are event rewards, not tier unlocks.

Cronen Osprey: The Only AR Worth Your Time

The Cronen Osprey fires at 882 RPM with a 30-round magazine and 70 levels of attachment grind . Its Apex attachment, the Cronen Helix Mk. II, converts it into a double-barrel receiver that fires on both trigger pull and release .

We have not tested this weapon post-launch. The 882 RPM stat sits between the M4 and Kastov 762, which suggests it will compete for the same mid-range role.

Do not grind tier 16 if you already main the Kastov 762. The Kastov received a medium damage and range buff in the Season 1 patch, alongside head, neck, and upper torso multiplier increases . The Osprey needs to outperform a buffed Kastov to justify the swap.

CSG-35: 1200 RPM, Zero Long-Range Viability

The CSG-35 hits 1200 RPM — the highest fire rate in the SMG class . Magazine size is 28 rounds with 112 reserve .

Its Apex attachment, CSG Crossfire, enables dual-wield akimbo .

Skip this weapon on open maps. The recoil becomes unmanageable past close range, per the official description . If you play Shipment or Cachette exclusively, the akimbo Crossfire build is your new primary.

The ISO Nightshade received a maximum damage range and minimum damage buff in the same patch . If you want a flexible SMG, the Nightshade outperforms the CSG-35 outside 10 meters.

The Patch That Reshapes the Meta

Season 1 buffed 13 weapons and nerfed three . These are the changes that affect your Season 1 weapon choices.

The Hyeon Burst nerf is the one that will catch players off guard. The Hyperburst Apex was a top-tier conversion in pre-season. It is now a damage trap.

What this actually means for your loadout: Do not buy Battle Pass tiers for the Hyeon Hyperburst. It is not worth the grind post-nerf.

What the Datamine Got Wrong

The MP5, SCAR-H, FMG-9, and butterfly knife exist in game files. None appear on the Season 1 roadmap.

Here is the catch: Datamined code is not a release schedule. The FMG-9 was name-dropped in a developer talk, confirming it will arrive eventually . The butterfly knife leaked in full. Neither has a date.

Do not build around the MP5 for Season 1. The current SMG meta stays intact until Season 1 Reloaded at the earliest.

Event Weapons: Wait, Do Not Grind

The JAK-12 shotgun and ZLR Talonhawk melee are in-season event rewards . Exact challenge requirements are unconfirmed.

Do not spend real money on Battle Pass tiers hoping to unlock these early. They are not on the pass.

We will update this section once the event goes live and the exact unlock conditions are verified in-game.

Is the MP5 in MW4 Season 1?

No. The MP5 exists in datamined files but is not on the official Season 1 roadmap. Expect it in a later season.

What tier unlocks the Cronen Osprey?

Tier 16 of the free Battle Pass track. It is not a premium-only unlock .

Did the Hyeon Hyperburst get nerfed?

Yes. Maximum damage dropped from 30 to 23, and the medium damage profile was removed entirely . The base Hyeon Burst is unaffected.

Is the CSG-35 good at range?

No. Recoil becomes unmanageable past close range, per the official weapon description . Use the ISO Nightshade for mid-range fights.

What is the best Season 1 weapon to unlock first?

The Kastov 762 is not a Season 1 weapon, but it received the biggest buff in the patch. Unlock the Cronen Osprey at tier 16 only if you want a new AR to test.
