There are Magnus and Devastator who come out of nowhere.The sound-resurection by Soundwave is unstable, Megatron wants the Matrix so he can be independent from him.The damage is also greater, akin to the Protoform invasion since there is a TV news broadcast of it. Unlike in ROTF with Alice, both had already left. A Megatron-loyalist Decepticon attacks Sam and Shige's dorm in attempt to find him.Both Megatron and Starscream are gonna attack Vegas. The big crazy shit - Las Vegas is powered by AllSpark energy harvested by Sector Seven, this information was revealed by a descendent of a First Seven of Sector Seven.Simmons runs a casino instead of his mom's deli.Instead of the frat party, we get a drag race.He leaks info regarding a Starscream attack to Optimus. Nothing like Ze French Lamborghini of TLK nor the G1 version of the character. sound because sound can resurrect dead Transformers. The quest to retrieve the AllSpark shard that revives Megatron isn't mentioned, which probably means Ravage, Reedman, etc.No Alice and none of that stupid infidelity sub-conflict. His personality and interactions with Sam aren't any different from the former. Sam goes to NYU instead of Princeton and instead of Leo we get an Asian named Shige.With that in mind The Fallen is absent from this script. Soundwave wins and goes to Earth to revive Megatron.

It opens with Starscream and Soundwave fighting for Decepticon leadership.
