EA continues the expansion of its "play4free" portfolio with the announcement of Command and Conquer: Tiberium Alliances, developed by Phenomic. The browser- and mobile-based strategy MMO will begin a closed beta on December 15. Interested generals can sign up at the game's official site.

The mobile Command and Conquer comes hot on the heels of last weekend's announcement of Command and Conquer: Generals 2, currently in production at BioWare Victory for launch on PC in 2013.
