EA Mythic officially closed Warhammer Online: Age of Reckoning servers on Wednesday.
The planned closure was due to the expiration of EA's licensing agreement with Games Workshop. The company said in a statement: "We wish to thank all the loyal players throughout the years for their patronage."
Warhammer Online launched in September 2008 and quickly amassed some 750,000 subscribers. However, despite positive reviews from the games press, more than half of those players had left by February of 2009.
In a lengthy statement earlier this year, producer Carrie Gouskos thanked fans for their support during Age of Reckoning's five years online.
"Games Workshop has cultivated a world class IP," she said at the time. "We were lucky enough to play in their universe for nearly a decade, with five great long years live. However, like all things - our contract has come to an end.
"Both Games Workshop and Mythic agreed to part ways, despite how hard it is emotionally on us to let the game go. It has been a tremendous honour to work with Games Workshop and even though we may be parting ways, our relationship with them remains strong."
Last year rival publisher Sega announced a partnership with Games Workshop which will see Total War developer Creative Assembly making multiple titles set in the Warhammer universe.
