Judging by the activity on the forum. Arma is a fairly obsolete entry in this unique style of gaming.
Anyone working on it all?
Does anyone even really play it anymore?
No! I'm Spamacus!

Based on the cooperative missions I see posted on Youtube, multiplayer is far from dead. FileFront just isn't as well known as some of the sites dedicated solely to the ArmA series.
Arma II is alive and kicking as before. Try armedassault.info - the most known website of OFP1 / ArmA series. Each day there is plenty of new addons and missions!
