The first War For Cybertron launched earlier this year and was well received due to its reverence for the original Transformers plot and characters. It was also pretty fun to play, but it did have some difficulty and technical issues.
Nothing a sequel can't fix though. Transformers will get a movie tie-in before the War For Cybertron sequel, with The Dark Of The Moon heading to PS3 next year. That one probably won't reference the original Transformers narrative though. Wonder what Michael Bay has come up with this time?
