The fourth and final issue of the bridging comic 'Alliance' has been released, and reveals some plot elements for the Movie itself.

- The company McClaren Robotics is a government front/cover for arriving at Transformers battle scenes and cleaning up any evidence of an alien presense at the scene. The only previous mention of McClaren Robotics was that actor Steve Tom was cast as McClaren Robotics CEO.
- An AllSpark fragment is seen in a government storage facility. The storage containment unit looks very much like the containment unit seen in promo pictures.
- In the issue, the Autobots discover that several Autobots have received the beacon call Optimus made at the end of the first movie. Five new Transformers are revealed in their vehicle modes: the Centennial Corvette (Sideswipe), three motorcycles (the Arcee bikes), and the Ice Cream truck.
- On the final page, the Autobots and human allies are in a dark command center as Optimus calls for the team to head out to Shanghai. Seen on the monitor is Demolishor. Although not all details can be made out due to the room being dark, one can clearly see Sideswipe and two of the motorcycles in their individual robot modes.

That confirms certain characters, and where the Movie will probably start from.

For those who haven't been following the IDW Movie Comics,
- 'Reign of Starscream' follows on from TF1
- 'Alliance' leads into TF2
- 'Defiance' is the historical flashback/backstory of the start of the war in the Movie Universe, that TF2 will probably be covering (with the 'new' Megatron) in their flashbacks.

Someone correct me if I'm wrong here, or left out anything.
