I have the PC version and thought it was pretty good. There was no difficulty level so it wasn't much of a challenge for me - headshots were easy cos the enemy barely ever moves once they transform . Was rather rewarding playing as Sideways and killing off the evil Autobots... Ironhide, Prime, Bumblebee etc. I prefer the keyboard but had to use the gamepad for the jets/heli cos the mouse wigged it out otherwise. There was alot of content to unlock which was pretty good. I seemed to enjoy free play as a car over some of the missions tho - great fun jumping off roof ramps and vehicle boost jumping at targets .

There arn't really that many bots to play as tho . When you get to Prime's and Megatron's stages they are made available to you. You can't unlock The Fallen or any other characters, even the drones like the F-18 could have been some fun to play as. The gameplay from character to character is varied enough and you can chain attacks together, triple punch - transform to car and then jump attack for a advanced takedown (which reminds me of the G1 opening where Jazz jumps at Skywarp - always liked that scene ).

It is a simple one scene at a time format - the levels arn't very big but they don't need to be. You unlock new levels and scenes as you advance. Hopefully there will be more DLC to add more to the game. It uses the Unreal 3 engine but doesn't support modding - which is a pity cos I have a Binaltech WRC/X and Masterpiece Starscream model that I would have liked to convert for gameplay .
