Quick answer
This is an independent fan-made guide focused on practical Cloudbreaker answers: builds, Engine Grid placement, parts, relics, bosses and progression.
How we verify
We prioritize official Steam and developer information, then use long-form gameplay footage to clarify how mechanics behave in the demo.
Version discipline
Demo observations stay labelled as such. Cloudbreaker released on September 15, 2026, and the launch window already saw Builds 1.0.1 (September 17), 1.0.2 (September 19), 1.0.3 (September 22) and 1.0.4 (September 29); patch-sensitive numbers are quoted with the build they were checked against.
Corrections
If a patch changes a mechanic, send the page URL and correction details to wuzhihun_shen@outlook.com.
Live-build note: Cloudbreaker released on September 15, 2026, and Build 1.0.1 (September 17) cut Scrap island payouts to 15–45 to fit current upgrade costs, Build 1.0.2 (September 19) delivered Steam Deck and high-resolution performance work, Build 1.0.3 (September 22) fixed the controller double-press, mission part counts and the upgrade-drawer preview bug, and made the game start in controller mode on the Steam Deck, and Build 1.0.4 (September 29) stopped Firing Line from slowing or shrinking parts that face away from it and cut chained Shield regen boost to 0.5. Anything still labelled as demo-sourced is being rechecked against the live build.
