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

Embedded with a supercomputer core, this latest-model W-Engine can compile operating code for machines at an astonishing speed, or quickly collect battlefield data to provide support for the whole squad. Of course, for Grace, this W-Engine is just a little toy for her to communicate with her "silicon-based children." "Looking carefully... you're handsome in your own way! Oh, it says in the manual that once it's sealed, it shouldn't be opened... Hmmm... Well, how would we know if we don't give it a try?!" — Grace, suddenly enthusiastic while holding the engine in her hand

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 Fusion Compiler in Zenless Zone Zero?

Fusion Compiler is a rank S W-Engine built for the Anomaly 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 Fusion Compiler?

Fusion Compiler fits Anomaly specialty Agents best, with 8 recommended characters including Miyabi, Grace, Yanagi — 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 Fusion Compiler, and where do I farm it?

Leveling Fusion Compiler through every milestone takes roughly 4 W-Engine components and Denny ×400,000, Anomaly Component ×4, Reinforced Anomaly 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 Fusion Compiler worth it?

Overclocking only strengthens Fusion Compiler'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 Fusion Compiler?

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.
