HawkOVR is a free, independent Windows x64 companion overlay for Diablo IV. It provides world-event information and configurable on-screen widgets, including Helltide worm and mystery chest indicators, so players can keep useful context visible without repeatedly switching to a browser. The overlay runs locally and a small launcher handles updates. Optional advanced features include behavior-tree actions, filtered pickup, skill auto-cast, and configurable Actor/Object display. Because those options may create inputs or change presentation, users should review current game rules and account policies before enabling them; every optional behavior can remain disabled. HawkOVR currently supports Diablo IV 3.1, and the public v1.0.1 download includes release details and a SHA-256 checksum. It has no subscription fee or premium tier. HawkOVR is not affiliated with, endorsed by, or sponsored by Blizzard Entertainment.
