Command and Conquer 4 Announced

[Bloo]

Uhmm, the idea is that as you play, you unlock stuff. Period. Both are combined, so playing online helps you in singleplayer and vice versa.


EDIT: Sorry to say, but seriously, did you even read the gamespot article at the top of the page?

Essentially, whenever you play Command & Conquer 4, be it in single-player, co-op, skirmish, or online, you earn experience that collects in your persistent player profile. Within the profile, you use your experience pool to level up your classes, earning new units, structures, powers, and upgrades. Since your profile is persistent across the game, you can then take your new toys and put them to use in any of our game modes.

Seems pretty clear to me.
