SAZ Parts System and Black Market dev video recap | Base vs additional options, weapon mastery, and analysis

On July 8, 2026, the official Sudden Attack Zero Point (SAZ) YouTube channel released "Build Your Ultimate Weapon!" — a roughly four-minute dev update in which the development team explains the game's flagship Parts System and Black Market in their own words. This article recaps the whole video, checks it against what the Final CBT actually shipped, and adds our analysis ahead of the early access launch.

Video at a glance

Recap 1 | Parts have two layers: base options and additional options

The video opens with the question that shaped the system: what if you could customize your favorite weapon to match your personal playstyle? Equipping parts in your weapon's customizable slots changes both its appearance and its performance, and part effects come in two categories.

Base options are, in the video's words, "the fixed core identity of a part." Two examples are shown.

Additional options are "randomly assigned when you acquire a part" — finer details that help you specialize. The video gives two examples.

• ADS accuracy when moving — for run-and-gun players
• ADS recoil control — for players who prefer to lock down a position

As the video puts it, "even two of the same parts can feel slightly different, making the hunt for your perfect combination a rewarding experience."

Recap 2 | Two ways to get parts: weapon mastery and play rewards

1. Weapon mastery — using a weapon unlocks its default parts sequentially (these come with no additional options). "Once you max out a weapon's mastery, you'll start earning crates for that specific weapon, which contain parts with random additional options. No SP or key cards required."
2. Play rewards — at the end of a match you have a chance to receive crates, but these require SP or a key card to open (key cards come from events).

Why do some crates need SP or key cards? The video's answer: part skins.

• Skins are cosmetic only
• They come in five grades: Common, Uncommon, Rare, Epic, and Legendary
• The team is emphatic: "We want to be very clear. Skins have zero impact on performance or stats."

Recap 3 | The Black Market is a player-driven hub built on SP

The final topic is the Black Market, "a player-driven hub designed to help you get the parts you want more easily."

• Sell parts you don't need to earn SP, then spend that SP on the exact part you're looking for
• Crates earned from playing can also be traded
• SP has other uses too: "use that SP to open crates and unlock characters"

The video closes by saying the Parts System and Black Market "are designed to add a new layer of depth and strategy" to SAZ, and invites viewers to the Final CBT (July 9–13).

How it lines up with the Final CBT

The video came out the day before the Final CBT, and most of what it describes was verifiable in the test.

• The Black Market was open during the CBT, with 200+ exclusive parts and 36 shared parts implemented. Our hands-on guide to the whole system is the Weapon Customization System explained article
• SP and key cards were handed out through CBT events — daily logins granted both (Final CBT OPENING Event guide)
• The opening cost the video leaves as "SP or key card" was confirmed in the CBT as one key card or 100 SP per crate (What are crates and how do you open them?)
• The same lineup carries over to early access on July 30, 2026 (release date and early access guide)
• Recoil changes from parts can be tested in Practice mode, which is confirmed for early access as well

Analysis | Performance from play, looks from luck and trading

What follows is our own reading of the design, not official information.

The "skins have zero impact" line is a trust commitment for a competitive FPS. The lottery excitement is pushed onto cosmetics, while performance-relevant parts are collected deliberately through mastery and trading. Stating it that bluntly in an official video reads as a deliberate answer to a market wary of pay-to-win.

At the same time, randomly assigned additional options are effectively a stat-rolling system. Chasing the perfect roll gives grinders something to pursue, but from a competitive-fairness standpoint the key question is how wide the performance gap between rolls can get. The four-and-a-half-day CBT was too short to measure this; we plan to test option ranges in early access and feed the results into the weapon list and tier guide.

The Black Market is an economy layer the original Sudden Attack never had. Player-driven pricing gives even unwanted parts resale value, raising the worth of every play reward. On the flip side, marketplaces like this traditionally wrestle with fees, listing limits, and bot/RMT countermeasures — and none of those details have been announced yet.

Finally, practical day-one moves that follow from the video's systems:

1. Pick one main weapon and push its mastery — default parts unlock as you play, and max mastery earns you that weapon's crates, free to open
2. Don't burn SP and key cards early — save them until you know which skins or parts you actually want
3. Sell unwanted parts on the Black Market instead of hoarding them — the SP goes toward crates or character unlocks

What the video does not cover

The following points are not addressed in the video and remain unconfirmed.

• The layout and number of part slots
• The full pool of additional options and their assignment probabilities
• Black Market fees, listing rules, and trade restrictions
• Whether SP can be purchased with real money (not mentioned in the video)

We will update this article and the Weapon Customization System guide as these are confirmed in early access.

Summary

• The official video covers the Parts System and the Black Market, straight from the dev team
• Part effects come in two layers: fixed base options plus additional options rolled randomly on acquisition
• Parts come from weapon mastery (default parts, then free weapon-specific crates at max mastery) and play-reward crates (opened with SP or key cards)
• Skins are cosmetic only, in five rarities from Common to Legendary — "zero impact on performance or stats"
• The Black Market lets you turn unwanted parts into SP and trade for exactly what you want, crates included
