EA community manager Aaron Kaufman has revealed that Command & Conquer 4 requires a constant internet connection to play.
"As of right now, you need to be online all the time to play C&C 4," he posts on the C&C Den, disguised as alias APOC (spotted by Voodoo Extreme). "This is primarily due to our 'player progression' feature so everything can be tracked.
"C&C 4 is not an MMO in the sense of World of Warcraft, but conceptually it has similar principles for being online all the time. While some may be taken aback by this, we've been testing this feature internally with all of our worldwide markets."
As he mentions, one of the big new features for Command & Conquer 4 is player progression which, like an MMO, will likely be tied to an account and stored on a server.
Command & Conquer 4 was announced recently as a PC-only title, which will appear in shops next year.
