What makes this wiki different
01 Co-op hub
Dedicated multiplayer wing
Crossplay, host setup, party limits, sync issues — all answered in one place instead of buried in forum threads.
02 Live map
18,020 markers, no autoplay
Resources, creatures, blueprints, POIs — all filterable, all deep-linkable. No video ads, no popups.
03 Patch-current
Updated every EA build
Each entity tracks last-verified date and the version it was checked against. Outdated data is flagged, not hidden.
