We all know that the game starts at the end, then we puts us through a flashback, from right after the first game ends, right? As Bumblebee takes a hit for Prime? We also know that the E3 demo was the end of the second chapter and the start of the third. We know that Jazz and Cliffjumper are sent to find the Dinobots and stumble upon the planet's ancient history. We have also seen Optimus getting captured by WFC!Megatron, (who even slaps him at one point). My guess is that Optimus gets freed and on his way out, he "kills" Megatron. Then we get the Decepticon story,which revolves around Starscream trying to force his way to the top. This means he butts heads with Shockwave (second E3 demo), and eventually ends up in charge of a group of loyalists: The Combaticons, who he uses to fight the Autobots in his own way, via subterfuge/sabotage (Vortex demo). Of course, Megatron returns in his new (Dark Energon infused? Not likely) body, and intrudes upon the building of Starscream's statue (gameplay trailer). After showing his number 2 what-for, he asserts his authority, with the Combaticons sucking up to him (based on Bruticus' official bio). He begins to launch direct assaults, either on Iacon (not likely) or on weak points in the Autobots' defences (such as fuel lines/ routes to energon mines/wells/whatever). This gets Optimus frantically trying to complete the Ark. I actually think the level where Starscream sabotages Shockwave's tower could be after this point, with him doing it out of spite, but we are supposedly introduced to him as a guy on-the-run, or something similar. The final stretch of the game will be the Autobots trying to make a comeback after having the Ark, and some of their strongholds (such as the abandoned city the Combaticons wreck) compromised. The knowledge that Cliffjumper gained allows Perceptor to come up with new ways to get Energon. Eventually the Ark launches, taking us back to the beginning, only this time we see it through Optimus' POV. He'll beat back Megatron, not doinig any serious harm, as the two ships pass through the Space Bridge, which of course collapses. This ending will allow High Moon to end the series, saying they crashed on earth, or allow them to carry on, saying they ended up on Junkion or something. I don't see the Dinobots being central to the plot, sadly, but I do think that we would see a least a bit of Grimlock butting heads with Prime, given that it's such a big part of his character. I think this will amount to one of his levels being his leading the Dinobots on an attack against the 'Cons, while Optimus is trying to conserve energon, or when Prime has asked him to do something else entirely (like helping with the evacuation?). This, I think, would fit in with his personality, which was described as making him the type to "fight and die" than "run and survive". As much as I like Shockwave, I doubt he'd be of any more importance than Heimdall was in Thor, so he would still get one or two cool moments (the website doesn't give him an ability, but didn't give one to 'Bee either, despite him being playable. Perhaps Shockwave can control the Insecticons, like Megatron and his hatchlings in DOTM, or anything else that could be seen as a spoiler). I don't think many people would mind if Perceptor missed out though. I'll add to this as I remember more of what I had in my mind. Feel free to discuss and critique, but try not to insult me! EDIT 1: Megatron's level would be part of him attacking the Autobots (he does lead from the front, and I'd assume that he'd have been MIA for some time. He wouldn't want to get rusty! Vortex's level takes place in an abandoned city, where I'd assume Prime wanted to hide the bridge. So, naturally, Bruticus would take it out himself. Sorry, forgot to make that clear. EDIT 2: After Trophy reveal: EDIT 3: EDIT 4: EDIT 5: EDIT 6: Bit late, but Metroplex's weakness may be the huge amount of Energon he clearly needs to function? EDIT 7: Moment of truth! And I can't believe I was actually almost right!
