You can now sign up to the open beta phase for Command & Conquer 4 Tiberian Twilight, which gives you the opportunity to test out the game's multiplayer component ahead of release on March 19, 2010.

The multiplayer features a 5 vs. 5 mode and four maps including the new Afflicted Arena. This new map features a once lush, Polynesian landscape transformed into a military dock by the Global Defense Initiative (GDI) and currently besieged by Brotherhood of Nod forces aiming to claim the tactically important location and take control of the Pacific Rim.

In the roles of the Offense, Defense and Support classes will engage in strategic battles to win key vantage points across the map and secure a majority of the TCN Hubs to take control of this vital location. Experience earned through the new Persistent Player Progression system during the multiplayer beta period will be transitioned to the full game upon its release
