Much better than expected, makes you feel 5 years old again.
The game tells a version of the Transformers last days on Cybertron, in which the Autobots want to leave and the Decepticons would rather they didn't. This plays out in several chapters, each played from a different perspective. For example, you start out with a brief Bumblebee match, and then get to kick *** as Optimus, Jazz, etc. There are also Decepticon levels, and the Combaticons are really fun. Of course, there's a nice long Megatron chapter, which is really the best.
Sounds quality is superb, especially the voice acting. They even peppered in some dialogue from the 1980s animated movie, which made me nerdgasm pretty hard.
Graphics are overall pretty good, although the occassional blurred texture shows up (like Megatrons vehicle form, which is pretty ugly). Still good for a twilight PS3 release.
Overall, a short but fun romp in the Transformers universe. I haven't gotten to multiplayer yet, but I'll update when I do.
