How to Get This W-Engine

Pull it from Signal Search using Master Tapes / Encrypted Master Tapes (bought with Polychrome) — S-rank W-Engines get their own banner, usually alongside the matching character's banner.

Trade for it at the Gadget Shop's Box Galaxy section (Sixth Street): costs W-Engine Components + W-Engine Chips + Denny; Chips come from disassembling spare W-Engines.

A handful of A/B-rank W-Engines unlock through Proxy Primer trials or as story/event rewards instead of the gacha — not every W-Engine is pullable.

Official Artwork / Lore

A supercomputing W-Engine equipped with a motion monitoring feature, perfectly matching the fast reflexes and combat maneuvers of Cat Thirens. Nekomata has added a foldable knife to its casing. Despite claiming that this design is to facilitate her in battle, the knife has fresh mackerel stains smeared onto it... "Lots of people call me a clever clogs for doing this mod, but when you're out on the streets, you gotta put everything you can to good use: Every little trick, every little thought, every little hustle... And look! A little kitty!" — Nekomata, diverting attention away while secretly trying to fish out the listener's wallet

How to read this W-Engine page

Every W-Engine has 5 Refinement ranks (R1→R5): refinement ONLY strengthens the passive effect — the numbers in the table above run from left (R1, unrefined) to right (R5, max refinement via 4 duplicates or Overclock materials); Base ATK and the Advanced Stat (CRIT Rate/CRIT DMG/ATK%/PEN Ratio/Anomaly Proficiency...) do NOT change with refinement, only with the engine's level. "Best Agents for this W-Engine" prioritizes agents whose real build actually recommends this engine; if that data isn't available yet, the page falls back to agents sharing the same specialty as a rough guide. "Alternatives of the same specialty" lists other W-Engines with the same role — useful when you don't own the engine shown on this page.

FAQ

What is Steel Cushion in Zenless Zone Zero?

Steel Cushion is a rank S W-Engine built for the Attack specialty in Zenless Zone Zero — equip it on an Agent of the matching specialty to unlock the full passive effect; see the base stats and the full R1→R5 Refinement table in the sections above.

Which Agents should use Steel Cushion?

Steel Cushion fits Attack specialty Agents best, with 8 recommended characters including Nekomata, Soldier 11, Corin — see the full list with portraits in the "Best Agents for this W-Engine" section above.

How much Denny and material does it take to upgrade Steel Cushion, and where do I farm it?

Leveling Steel Cushion through every milestone takes roughly 4 W-Engine components and Denny ×400,000, Attack Component ×4, Reinforced Attack Component ×32 Denny combined — the components drop from Combat Simulation; see the exact breakdown per milestone and the Battery cost in the "How Much You Need" and "Where to Farm" sections above.

Is Overclocking Steel Cushion worth it?

Overclocking only strengthens Steel Cushion's passive effect from ★1 up to ★5 (5 copies) — it never changes Base ATK or the sub-stat, so getting the base copy matters far more; treat extra copies as a bonus.

Where do I get Steel Cushion?

Mostly through Signal Search gacha (Polychrome); a few A/B-rank W-Engines are tradeable at the Gadget Shop's Box Galaxy or come from story/event rewards — see the "How to Get" section above for details.
