EA is conducting a new survey and in exchange for allowing marketers to harvest our brain juice, they revealed some hints about Command & Conquer 4.

It's a long survey with a lot of standard questions like "What systems do you own?" and "Do you play demos before buying games?" However, there were a couple interesting bits. One question, for example, gauged my interest in the following description:

"Command & Conquer 4 allows C&C fans to finally experience the epic conclusion to the 15-year Tiberium saga with innovative RPG-like player progression, persistent in both single player and Multiplayer modes, co-op play, and new stylized, live-action cinematics."

A later question then asked my opinion on these hypothetical features:

• Play in the first RTS game with MMORPG like player progression in which you are rewarded every time you play. Every unit you kill in single player, multiplayer, or skirmish gives you experience points that allows you to level up your abilities and unlock new units, powers, and upgrades to your arsenal.
• Play with all new, bigger and badder, units from GDI and Nod, including the Crawler, the first ever mobile base in RTS games
• Play the campaign on your own or tackle it with a friend, as co-operative campaigns return
• Play in epic 5 vs 5 online multiplayer with all new objective-based game modes Introducing the first mobile base in RTS games: The Crawler. Focus on the action as the Crawler becomes your all-in-one base, which can be deployed and redeployed anywhere on the battlefield for even more strategic options
• Dive into an all-new story written by a new scriptwriting team and told through trademark C&C cinematics taken to the next level with grittier, stylized FMVs in the vein of Minority Report.
• Play in the first ever class-based C&C game - a new challenge for C&C and RTS players to master.

The survey's here if you're passionate about the series and want to make sure your vote is counted. The information listed above are the only potential C&C4 details that were revealed throughout, though.
