The CSG-35 is one of the new SMGs arriving in Call of Duty: Modern Warfare 4 and Warzone Season 1. With an exceptionally high fire rate and strong close-range potential, it is worth adding to your weapon collection, especially if you prefer aggressive playstyles. The good news is that you can unlock it through the free Battle Pass reward track without purchasing BlackCell or the Premium Battle Pass. For players who want to speed up their overall progression, MW4 Boosting can also be a consideration alongside regular in-game challenges.
However, reaching the required Battle Pass tier still takes some consistent playtime. Our team recommends prioritizing challenges and choosing modes that reward both objective participation and combat performance. Below, we explain how to unlock the CSG-35, which activities can help you progress faster, and what makes its exclusive CSG Crossfire attachment worth trying.
CSG-35 Unlock Requirements in MW4 and Warzone

The CSG-35 is available at Tier 36 of the Season 1 Battle Pass, making it a free reward for all players. You do not need to purchase the Premium Battle Pass or BlackCell to obtain the base weapon.
The CSG-35 is a free Tier 36 Season 1 Battle Pass reward. You do not need to purchase the Premium Battle Pass or BlackCell to unlock the base weapon.
Here are the main unlock details:
| Requirement | Details |

| Unlock Method | Season 1 Battle Pass |
| Required Tier | Tier 36 |

The Season 1 reward track also includes a CSG-35 weapon blueprint at Tier 73, while BlackCell offers another blueprint as a premium reward. Keep in mind that these blueprints are separate from the base weapon unlock. You can check the official Call of Duty Season 1 announcement for the weapon's Battle Pass details.

For players working toward Tier 36, there is no need to spend money on an additional Battle Pass upgrade. Focus on earning Battle Pass XP and claim the free weapon reward once you reach the required tier.
How to Unlock the CSG-35 Faster
The most straightforward way to unlock the CSG-35 is to earn Battle Pass XP consistently across MW4 Multiplayer, DMZ, and Warzone. Rather than relying entirely on regular match progression, our team recommends combining daily and weekly challenges with modes that suit your preferred playstyle.
Complete Daily and Weekly Challenges
Daily and weekly challenges should be among your first priorities. They provide additional XP and give you specific objectives to work toward instead of playing matches without a clear progression goal.
Before entering a match, check the available challenges and identify objectives that can be completed together. For example, if several tasks involve weapon eliminations or objective play, choose a mode where you can make progress on multiple requirements in the same match.
We recommend checking your challenge list regularly, especially when weekly objectives become available. Completing these tasks consistently can make Battle Pass progression feel much less repetitive.
Best Multiplayer Modes for Battle Pass XP
In Multiplayer, objective-based modes are useful because they reward more than simply chasing eliminations.
| Game Mode | Why We Recommend It |
|---|---|
| Hardpoint | Frequent objective fights provide opportunities for kills and objective score |
| Domination | Capturing and defending points creates consistent opportunities to earn XP |
| Hijack | A useful option for players who prefer active objective-based engagements |

Our team generally favors objective-focused play over spending an entire match chasing kills. Staying near objectives, supporting teammates, and completing relevant challenges can make each match more productive.
Use Warzone Resurgence for Consistent Progress
Resurgence is another worthwhile option for players who prefer Warzone. Its shorter match structure and frequent engagements give you more opportunities to participate in combat without committing to the longer pace of traditional Battle Royale matches.
To make your sessions more productive:
- Prioritize daily and weekly challenges that can be completed in Resurgence.
- Stay active in engagements instead of spending too much time avoiding combat.
- Play with a coordinated squad to improve survival and objective efficiency.
- Activate Double Battle Pass XP tokens when you have enough time to make meaningful use of them.
Make the Most of Double Battle Pass XP Tokens
Double Battle Pass XP tokens can help accelerate progression, but timing matters. We recommend activating them before a focused play session rather than using them when you only have a few minutes available.
Combining these tokens with challenge completion is a practical way to get more value from your playtime. However, remember that Battle Pass progression and weapon leveling are separate systems. Reaching Tier 36 unlocks the CSG-35, while using the weapon in matches helps you progress through its weapon levels.
CSG-35 Stats and CSG Crossfire Apex Attachment
Once unlocked, the CSG-35 offers a distinctly aggressive SMG playstyle. Its standout characteristic is its 1200 RPM fire rate, which allows it to deliver rapid follow-up shots during close-range encounters.
Here are its available base weapon statistics:
| Weapon Stat | CSG-35 |
|---|---|
| Weapon Class | SMG |
| Maximum Level | 42 |
| Magazine Capacity | 28 Rounds |
| Reserve Ammunition | 112 Rounds |
| Fire Rate | 1200 RPM |
| Apex Attachment | CSG Crossfire |
What Makes the CSG-35 Effective?
The CSG-35's high fire rate makes it particularly dangerous in close-quarters combat. Within approximately 20 meters, its rapid shots can put considerable pressure on opponents, especially when you catch them moving through buildings, corridors, or other confined spaces.
However, a high fire rate does not automatically make a weapon effective at every distance. The CSG-35 has relatively modest damage per shot, and its recoil becomes more difficult to manage during longer engagements.
From our team's perspective, positioning is more important than simply firing as quickly as possible. Try to close the distance before engaging, use available cover, and avoid challenging opponents who have a clear advantage at medium or long range.

CSG Crossfire: The Exclusive Dual-Wield Attachment
The CSG Crossfire is the CSG-35's Apex Attachment, and it changes the weapon's handling by converting it into a dual-wield Akimbo setup.
Its main characteristics include:
- Converts the CSG-35 into dual-wield weapons.
- Increases magazine capacity from 28 to 30 rounds per weapon.
- Reduces reserve ammunition from 112 to 90 rounds.
- Sacrifices accuracy in exchange for a more aggressive close-range shooting style.
The attachment is best suited to players who prefer rushing opponents and fighting at extremely short distances. The dual-wield setup can create intense pressure during close-range encounters, but reduced accuracy makes it less suitable for situations requiring precise shots.
We recommend experimenting with both configurations rather than assuming Akimbo is always the better choice. Standard CSG-35 handling offers more control, while CSG Crossfire favors aggressive pushes and close-quarters engagements.

Is the CSG-35 Worth Unlocking?
Yes, the CSG-35 is worth unlocking if you regularly use SMGs and prefer fast-paced combat. Its 1200 RPM fire rate gives it a clear identity, while the CSG Crossfire attachment provides an alternative way to approach close-range fights.
However, its strengths come with limitations. Modest damage per shot and increasingly difficult recoil control at longer distances mean that it is not an ideal choice for every engagement.
Here is how we would approach using it in different situations:
| Game Mode | Recommended Approach |
|---|---|
| MW4 Multiplayer | Use its high fire rate in close-range objective fights |
| Warzone | Consider it for aggressive close-range engagements |
| Resurgence | Take advantage of frequent encounters and fast-paced combat |
| Medium-Range Fights | Control recoil and avoid unnecessary extended engagements |
Players who enjoy rushing, flanking, and fighting inside buildings will likely get the most out of this SMG. Those who prefer holding longer sightlines may find other weapon classes more comfortable.
If you regularly play DMZ and want to improve your overall in-game economy, you can also explore options such as buying CoD MW4 DMZ Money. However, DMZ currency progression is separate from the Battle Pass XP required to unlock the CSG-35, so it should not be confused with the weapon's unlock requirement.
Summary
Unlocking the CSG-35 in MW4 and Warzone does not require a premium purchase. You simply need to reach Tier 36 of the Season 1 Battle Pass and claim its free reward.
Our team recommends combining daily and weekly challenges with objective-based Multiplayer modes or Warzone Resurgence to maintain consistent progression. Double Battle Pass XP tokens can also help when used during focused play sessions.
Once you have the weapon, experiment with its standard configuration before trying the CSG Crossfire attachment. The CSG-35 is built around aggressive close-range combat, and understanding when to take fights at short distances will help you get more value from its exceptionally high fire rate.
