MAG released almost a year ago, but according to Zipper Interactive's community boss, Jeremy Dunham, the game is still going strong and is surpassing SOCOM Confrontation.
Responding to a post on the official MAG forums, which stated that MAG was struggling to post figures similar to SOCOM Confrontation, Dunham said "This is incorrect - MAG has more concurrent players than SOCOM Confrontation worldwide on a daily, weekly, and monthly basis. This has been true for every month since MAG's release on January 26."
He went on to say "Obviously we don't hit the same numbers we had in our first few months in terms of concurrent and daily users, but we're still amongst the most played online PS3 games out there."
Zipper are working on a new SOCOM game at the moment, but they haven't stopped supporting MAG and recently released some new DLC and the MAG 2.0 patch.
