The short answer
The current official platform list does not include Xbox. It names Windows and Mac, PlayStation 5 and Nintendo Switch 2, while the FAQ says there are no other platform plans listed in the current information. Check the official source date when revisiting this answer because platform availability can change after launch.
Why crossplay does not help
Crossplay connects supported versions to the same world; it does not let an unsupported platform enter that world. If Xbox has no Big Walk version, an Xbox account cannot simply use crossplay to join a PC, PS5 or Switch 2 session. The correct order is to verify platform availability first, then read the crossplay page.
What Xbox players can do now
Use the official platform pages to watch for a direct Xbox listing or announcement, and do not rely on a third-party wishlist or search snippet as confirmation. If you own a different listed platform, use its dedicated page and plan around the supported co-op rules. Do not buy a different version assuming the Xbox player can join later.
Do not guess a port date
The current material gives no confirmed Xbox release date, price or technical requirements. A future plan, if announced, would need an official source before this page changes from “not listed” to “available.” Until then, any month, window or rumor is待确认 and should not be written as a schedule.
How the source check works
The page uses the official FAQ, the official Press Kit and the official platform list as the primary evidence. Search volume shows that Xbox is a real player question, but search demand does not prove a product release. Recheck those official pages when updating the article and record the date in the opening answer.
The purchase decision
If your entire group is on Xbox, Big Walk is not currently a confirmed purchase for that group. If the rest of the group uses PC, PS5 or Switch 2 and one person has access to a listed platform, that person can evaluate the game there, but it is not the same as native Xbox availability. Keep the platform boundary explicit.
What remains pending
A future Xbox port, Game Pass inclusion, cross-save behavior and Xbox-specific controller details are all待确认 because the current official list does not provide them. This page will be useful only if it keeps the present answer date-stamped and updates from a first-party announcement. It should never turn silence into a permanent “never.”
Field test noteDo not write “never on Xbox.” Replace the current answer only after an official platform page or announcement changes.
