Transformers: Fall of Cybertron will be out tomorrow, so it stands to reason we see a launch trailer today.
A healthy mix of gameplay bits, cutscenes, and CG trailers past, the video tells that familiar story of Cybertron, wracked by endless conflict and on the verge of death. Optimus laments, as he tends to do, and Decepticons just don't give much of a crap. You know how it is.
Of course the Dinobots are part of this whole war, and we see some of Grimlock's melee action here and there. The last few seconds give us a quick look at what is likely the Ark.
It's been previously confirmed that both Dinobots and Insecticons will be added to multiplayer post-launch as DLC, though likely as vanity skins rather than actual playable characters.
