Hello Warriors,

The wait is almost over. After weeks of work behind the scenes, we are proud to announce the official date of the ThunderMU Grand Opening.

Grand Opening: October 30, 2026.

Server goes live at 17:00 UTC.

Until then ThunderMU remains under construction while we finish testing, balancing and polishing every part of the game — from events and drops to stability and performance — so that when the gates open, everything feels exactly as it should.

Some parts of the website may change or be temporarily unavailable while the work is in progress. Thank you for your patience and support.
