I have to say that I didn't pay much attention to the movie Transformers: Revenge of the Fallen. Still, I will say that the game has a lot to do with the plot - no matter it's very random. In fact, what is happening in the game is very simple - the bad guys are trying to awake the ultimate villain Megatron and the good guys are helping humanity to stop them. That's basically what's the game is about.
After each mission you will have the opportunity to distribute some skill points and upgrade your robot. For example, lowering the time before your weapons cause malfunction. Every robot has a typical and in my opinion funny name, accompanied by unique skills and weapons.
Everything would be great if the action, which is the core of the game, didn't look like being in a slow motion movie. The robots are somehow too massive and slow. Add the control system problem and strange combinations such as "Press shift, press space, release shift without releasing space" and you get a disaster. You will often be in situations where the lack of dynamics will make the orientation impossible, and it gets even worse if your PC is not powerful enough.
