Red Alert 3 will mostly be a "What If?" kind of game which looks into the possibilities the first two games didn't cover. Classic technologies like Tesla coils, teleportation, and time traveling will be supplemented by new innovations like armored bears, floating island fortresses and... get this, intelligent dolphins!
Some of the interesting features that will be making its way into the game include a first ever heard of co-op campaign mode, a focus on the naval combat aspects, and all the Kalashnikov designer rifles a Command & Conquer game can hold.
More info as it becomes available!
