Weapon Crates & Key Cards in Sudden Attack Zero Point
Open Weapon Parts Crates, event Key Cards, and smart SP decisions during Early Access.
Open Weapon Parts Crates and Key Cards are the RNG layer of Sudden Attack Zero Point progression. Nexon highlighted both during Final Closed Beta events and Early Access previews: crates dispense weapon parts and skin modules, while key cards gate higher-value opens or bonus rolls during Check-in, Playtime, Victory, and Black Market event tracks. This guide explains how crates fit beside match SP and the Black Market, when to open versus sell, and how to avoid bankrupting your build plan on day one.
Baseline economy terms live on the Items hub; trading tactics on Black Market Items.
Why crates exist in SAZ
Sudden Attack Zero Point wants two parallel feelings:
- Deterministic skill — win rounds, earn SP, buy the part you practiced in Practice mode.
- Collection excitement — open crates for surprise exclusives and cosmetics.
Crates feed the second loop without replacing the first. You can reach competitive readiness without gambling every Key Card the moment it drops.
Open Weapon Parts Crate — what it targets
Press language describes Open Weapon Parts Crates as sources for:
- Primary-exclusive parts (from the 200+ pool)
- Shared attachments (from the 36 pool)
- Skin / cosmetic part modules that drive Black Market demand
Exact drop tables will shift with Updates. Assume launch crates overweight common modules and sprinkle rares — classic F2P distribution.
Key Cards — the event multiplier
Key Cards appeared in Final CBT Daily Login rewards and similar tracks. Functionally they are:
- Tokens that unlock or upgrade crate opens during timed events
- Sometimes required to open event-tagged crates instead of standard ones
- Account-bound progression items (do not expect free Steam trading of cards outside Nexon rules)

Open vs sell — decision framework
| Situation | Action |
|---|---|
| You still lack a viable main primary build | Open crates that can drop shared attachments for that gun |
| You already finished a loadout | Sell duplicate or off-meta pulls on the Black Market |
| A limited event crate has unique cosmetics | Open a budgeted number; sell extras |
| SP is below your next planned buy | Prefer selling junk pulls over re-rolling |
Never open crates “for dopamine” when you are three shared grips away from a stable spray.
Linking crates to the Black Market
Crates create supply. The Black Market discovers price.
- Open during launch week when you need coverage.
- List duplicates quickly before the market floods.
- Buy missing exclusives with SP from sales + match income — see Black Market Items.
- Revisit prices after every balance patch on Updates — buffed guns inflate their exclusive parts.
Event stacking with crates
During Early Access launch week:
- Clear Check-in for Key Cards / SP.
- Hit Playtime thresholds without forcing burnout queues.
- Secure Victory crate rewards with Bot→live warm-ups from Practice & Bots.
- Only then spend Key Cards on premium opens.
This order mirrors Final CBT event design and keeps RNG after guaranteed progress.
Risk notes
- Crates may include chance-based rewards (Steam already flags chance-based purchases for the title).
- Real-money crate offers — if any appear — are optional; core F2P loops remain free per Nexon’s Steam FAQ.
- Outside-client “crate codes” from random Discord DMs are scams — stick to Official Links.
