GameInformer- After numerous extensions, ATLUS confirmed it will finally turn off the North American servers for Demon's Souls on May 31, 2012.
The servers will officially turn off at 11:59 PM PST. ATLUS says the single-player portion of the game will remain unaffected. The company will have two separate World Tendency events next month, May 1-15 and May 16-31, based on fan voting.
ATLUS encourages all players to sign on May 31 one last time before saying goodbye.
