As the first issue of the mini-series is due for release in July, this is a good time to catch up on the story as it begins - though be aware there are spoilers for the ongoing Optimus Prime series, too - and make sure to check out our review of the opening issue here.
Not a whimper, nor a bang-the end comes with a squall of entropy shrieking from the ravenous maw of death itself. The message is clear: Unicron has arrived. The Transformers lock into a desperate bid to save Rom's homeworld from the world-killer - but why has Unicron chosen this world on his path to Cybertron... and Earth? The biggest story in the history of Transformers starts now: for Unicron's arrival can mean nothing less than the end of a universe.
