Transformers: Fall of Cybertron/Awesome

"Megatron: No one leaves without my permission!
 * Ironhide punching out Starscream when the latter tries to attack Optimus Prime (who was carrying a wounded Bumblebee at the time) in the premiere trailer, thus proving that such heroic nonsense can still make a difference.
 * And a little after that, Grimlock's transformation. Complete with the ability to shoot fire from his mouth.
 * The whole trailer being set to Puscifer's "The Humbling River" is delicious icing on the awesome cake.
 * What we've seen of the fight between Optimus and Megatron from the gameplay trailer, made all the more awesome after the behind the scenes video which gave us some dialogue from it:

(Optimus blocks Megatron's strike)

Optimus Prime: I wasn't asking."

"METROPLEX HEEDS THE CALL OF THE LAST PRIME.
 * In the E3 2012 trailer, Optimus Prime summons Metroplex.

 * We've also got Grimlock and Bruticus going at it until Jazz jumps in. Literally. Jazz jumps onto Bruticus' head. And then the other Dinobots join the fray, with Snarl ramming one of Bruticus' legs hard enough to make him stumble. Then Bruticus gets right back up and backhands Swoop.
 * It doesn't last too long, but Optimus takes on Megatron, Shockwave and Starscream all at once. He manages to take down Shockwave and then Starscream before Megatron overpowers him. Then Optimus calls in Metroplex.
 * Matt Tieger gets a meta example. The Dinobots were going to be retired for irrelevance to Transformers in general- so he managed to eventually persuade Hasbro to reconsider; this was done by creating a new origin story and citing it as a chance to shake up the gameplay. And thus we got the Dinobot awesomeness.
