Codes and redeem rewards
No official code list, redemption menu or promotional reward system was verified on the Steam page checked August 12, 2026. Require a developer or official-store source for any claimed code. Do not download a “code generator” or provide a Steam login to third-party sites.
Languages
Steam lists English, German, Japanese, Korean, Brazilian Portuguese, Russian, Simplified Chinese, Ukrainian, French, Latin American Spanish and Traditional Chinese. English is marked for full audio. Check the live Steam language table for the current interface, subtitle and audio columns.
Controller and Steam Deck
The listing currently has no controller-support category. That does not prove controllers cannot work through Steam Input, but it means native or complete support should not be promised. Likewise, no Valve Deck rating appeared in the checked official source. Wait for an official rating or label any hands-on result with the exact device and settings.
How to read missing store fields
This page distinguishes “not listed” from “not supported.” The official snapshot can confirm the modes and categories it contains, but it cannot establish a permanent decision about absent features. No demo link means there was no verified official demo attached at the access time; it does not rule out a later test build. A missing price does not mean the game is free, and a missing achievement category does not establish a final achievement policy.
The same rule applies to input. Without a controller category, native and complete controller operation is unverified. Steam Input may allow a device-specific layout, but that would be a user configuration, not evidence of official support. A Valve Deck rating must be reported separately from an individual handheld test.
What to recheck after release
Review the live store page for price changes, demo availability, controller categories, Deck status and achievement details. Keep the access date when sharing an answer so readers can distinguish a current fact from an older pre-release snapshot.
For the confirmed and still-unknown network details, read the co-op guide. Hardware and broadband requirements are in the PC requirements guide.
