There is a lot to digest in the above developer diary for Command & Conquer 4: Tiberian Twilight. Not only does it show the benefits of each class in the game, but it also reveals the new mission and player progression system. This time around, players will not only unlock things as they go along (utilizing a level-based system), but also given a choice during the campaign early on: stick with GDI or align yourself with series bad boy Kane and his NOD forces.
Either way you choose to go, one thing is certain: this is the end of the Tiberium storyline. Bass says that doesn't necessarily mean the door to the universe is shut forever, but that this particular story thread will conclude with C&C4.
