The Weapon Customization System in Sudden Attack Zero Point (SAZ) lets you combine parts earned in-game to tune recoil, reload speed, and appearance to fit your playstyle. The Final CBT included more than 200 Exclusive Weapon Parts and 36 Shared Weapon Parts, and the Black Market — where you can trade earned parts and skins with other players — was also open. The same lineup carries over to the early access launch on July 30, 2026 (release date and early access guide). This article summarizes what is known so far from the official developer video and news coverage.

Weapon Customization System overview
On July 8, 2026 (JST), Nexon released "Build Your Ultimate Weapon!", a developer video introducing weapon customization and the Black Market. This is a flagship system that did not exist in the original Sudden Attack: the same weapon can feel completely different depending on its parts configuration, letting you build a gun that is truly your own.
The customization-related content available in the Final CBT is as follows.
| Item | Included in CBT |
|---|---|
| Primary Weapons | 13 |
| Secondary Weapons | 4 |
| Exclusive Weapon Parts | 200+ (including various skins) |
| Shared Weapon Parts | 36 |
Exclusive parts fit a specific weapon, while shared parts can be used across multiple weapons. For weapon stats and recommendations, see the weapon list and tier guide.
What customization can change
Official announcements and media coverage explicitly mention the following three elements.
- Recoil: parts change how the weapon kicks when firing
- Reload speed: you can adjust how long a reload takes
- Appearance: skinned parts change how the weapon looks
Official messaging says you can "adjust recoil, reload speed, and more to fit your playstyle," so parts affecting other stats may exist. We will update this article with detailed attributes and numbers as they are confirmed during the CBT.
How to get parts (during the Final CBT)
During the CBT, in-game events provide ways to earn parts.
| Event | Reward |
|---|---|
| Daily login | SP (currency), Key Cards for opening Crates |
| Playtime milestones | SP (currency) |
| Match wins | Epic Skin Parts Crate |
| Black Market event | Event Tokens for completing missions |
The core loop appears to be opening Crates with Key Cards to obtain parts. Since Key Cards accumulate just by logging in every day, CBT participants should make sure to clear their dailies. For the CBT schedule and how to join, see the Final CBT complete guide.
What is the Black Market
The Black Market is a system that lets you trade items earned through gameplay — such as weapon skins and parts — with other players. It is open during the Final CBT, and the intended flow is to trade for the parts you want, complete your gear, and strengthen your Loadout.
Black Market events are also running during the CBT, and completing event missions rewards you with Event Tokens.
Information not yet confirmed
The following items have no confirmed official information yet, so this article leaves them open.
- Part attachment slots (barrel, magazine, stock, and other slot categories)
- Exact stat changes provided by each part
- The full parts rarity system (the crate name hints at an "Epic" tier)
- Black Market details such as trading currency and fees
- Customization changes planned for the full release
If you are new to SAZ, we recommend covering the basics in the beginner guide before diving into customization.
