SOE’s confirmed in this forum post that The Matrix Online’s servers are to be turned off on July 31.
The MMO’s been running up for four years.
“It has been a good run. Where many games have fizzled out before or shortly after launch, by August we will have lived on in our home at SOE for more than four years. To this day, I have never worked with a community as dedicated as The Matrix Online community,” said producer Dan Myers.
