The newest Command & Conquer game will differ greatly from the old C&C games. EA have now released a gameplay trailer of the campaign “Transport Down”.
C&C4 Fractions & Classes
C&C4 will be different. Most importantly, there will be many RPG elements and units will be upgradable (as we know it from C&C Generals).
You can play the following fractions & classes:
Two fractions: The Global Defense Initiative and The Brotherhood of Nod.
Three classes: offense, defense and support
Another very important change is that there is no longer the need to build a base. The crawler is basically an all-in-one unit that includes a radar, war factory and more. Defense crawlers can still build all of the traditional buildings.
