MW4 Season 1: Unlock the 4 New Guns

Updated 6 November 2026 · Standard formula, shown below

Modern Warfare 4’s Season 1 adds four new weapons, and unlocking them requires specific in-game challenges or the purchase of the Season 1 Battle Pass. This guide explains exactly how to unlock each gun, the requirements, and tips for completing the challenges quickly.

Overview of the Season 1 Weapons

Season 1 introduces a mix of weapon classes to suit different playstyles. The four new guns are:

TR-76 Geist – a bullpup assault rifle with high damage and moderate recoil.
ISO 9mm – a submachine gun with a high fire rate and excellent mobility.
KVD Enforcer – a marksman rifle that excels at medium-to-long range.
Dual Kamas – melee weapons that allow for quick, dual-wielded strikes.

Each weapon can be unlocked through either the Battle Pass or a separate in-game challenge. The challenge method is permanent, so you can unlock them even after the season ends.

How to Unlock Each Weapon

Here are the specific unlock requirements for each gun:

TR-76 Geist: Reach Battle Pass Tier 31, or complete the challenge “Get 25 operator kills with an assault rifle while using the Vaznev-9K as your primary weapon.”
ISO 9mm: Reach Battle Pass Tier 15, or complete “Get 10 hipfire kills with an SMG while moving.”
KVD Enforcer: Reach Battle Pass Tier 47, or complete “Get 20 one-shot kills with a marksman rifle.”
Dual Kamas: Reach Battle Pass Tier 52, or complete “Get 15 kills with a melee weapon.”

All challenges must be done in multiplayer or Warzone (not in private matches or against bots). Progress tracks across both modes.

Battle Pass vs. Challenges: Which Is Faster?

The Battle Pass route is generally faster if you play regularly, as you earn tier progress through match XP and daily challenges. However, if you prefer not to spend money, the challenges are free but can take longer depending on your skill level. For example, getting 25 operator kills with an assault rifle while using a specific primary is time-consuming if you don’t main that weapon. In contrast, the ISO 9mm challenge (10 hipfire kills while moving) can be done in a few matches with an SMG loadout.

If you’re aiming for efficiency, focus on the challenges that align with your playstyle. For instance, if you’re a sniper, the KVD Enforcer challenge (20 one-shot kills) will come naturally.

Tips for Completing the Unlock Challenges

Here are some practical tips for each challenge:

TR-76 Geist: Use the Vaznev-9K as your primary and any assault rifle as your secondary. Play objective modes like Hardpoint or Domination where enemy locations are predictable. Use attachments that reduce recoil for easier mid-range kills.
ISO 9mm: Equip an SMG with a laser sight and a stock that improves hipfire accuracy. Play Shipment or a small map, and constantly move while firing. Slide-canceling can help maintain momentum.
KVD Enforcer: Use a marksman rifle like the EBR-14 or SA-B 50. Aim for the head or upper chest. Hardcore modes make one-shot kills easier, but be aware that enemy health is lower, so you might need to adjust your aim.
Dual Kamas: Play a mode like Kill Confirmed and use the Double Time perk to close distances. Use smoke grenades to get close to enemies. Alternatively, play Warzone and use the melee weapon in close-quarters situations.

Common Problems and Misconceptions

One common issue is that players think the challenges must be done in a single match. That’s not true; progress carries over across matches. Another misconception is that you need to own the Battle Pass to unlock the weapons via challenges. You don’t – the challenges are available to everyone. However, if you buy the Battle Pass, you unlock the weapons instantly at the specified tiers, and you also get the challenges as an alternative for later seasons.

Another problem is that some challenges might not track properly if you leave a match early. Make sure to finish matches for progress to count. Also, if you’re using a blueprint that changes the weapon’s name, the game might not register the kill for the challenge – use the base weapon to be safe.

Comparing the New Weapons

Here’s a quick comparison to help you decide which to prioritize:

TR-76 Geist – Best for players who want a hard-hitting AR with a unique look. It has slower fire rate than the M4 but higher damage per shot.
ISO 9mm – Ideal for aggressive, run-and-gun play. It has a fast time-to-kill at close range but struggles at longer distances.
KVD Enforcer – A solid choice for medium-range engagements. It’s semi-automatic, so it rewards precise shooting.
Dual Kamas – Purely for melee enthusiasts. They’re fast and fun, but you’re at a disadvantage against guns.

If you can only unlock one, the ISO 9mm is the most versatile for multiplayer, while the KVD Enforcer is great for Warzone.

Frequently Asked Questions

Do I need to buy the Battle Pass to unlock the new weapons?

No. You can unlock all four weapons by completing the in-game challenges, which are free. The Battle Pass simply gives you instant access at certain tiers, so you don’t have to grind the challenges.

Can I unlock the weapons after Season 1 ends?

Yes. The challenges remain available after the season ends, so you can unlock them anytime. However, if you don’t complete the Battle Pass before the season ends, you lose the chance to get the instant tier rewards.

Do the challenges work in Warzone?

Yes, both multiplayer and Warzone count toward the challenges. However, some challenges may be easier in one mode or the other. For example, the melee challenge is easier in multiplayer due to smaller maps.

What’s the best way to get the TR-76 Geist challenge done quickly?

Use the Vaznev-9K as your primary and an assault rifle like the M4 or Kastov 762 as your secondary. Play Hardpoint and focus on defending the objective. Use attachments that improve recoil control and aim for the chest or head.

Are the new weapons overpowered?

Based on initial community feedback, the TR-76 Geist and ISO 9mm are strong but not overpowered. The KVD Enforcer is good but not meta, and the Dual Kamas are situational. Balance changes may occur in future updates.

Final Thoughts

Unlocking the four new weapons in MW4 Season 1 is straightforward if you follow the challenges. Prioritize the ones that match your playstyle, and don’t forget to finish matches for progress to count. Whether you grind the challenges or buy the Battle Pass, these weapons add fresh variety to your loadouts.
