Favorite campaign moment *spoiler alert* - The mad escape to fly out of Trypticon after destroying his transformation cog...I absolutely LOVED flying out of the closing mouth, really reminded me of the space slug in empire strikes back. I actually was laughing in glee during the whole sequence

Favorite multiplayer moment(s) - Playing control points as an autobot soldier (don't remember the map), but I was damaged and booking down a looooong corridor in tank mode to pick up an energon cube. Some foolish decepticon plinked me from behind and I did the 180 turn to find him dead in my sights. One big cannon shot from extreme distance = one dead decepticon. It was great!
Another was playing as a scientist in the Bomb mode on the orbital debris map. A grouping of players were duking it out on the upper dish section near the edge and I landed and shockwaved a few of them right off the edge. Also a very fun moment.
