I won't say the game is amazing, because it's not. It's not anything new, really. Truly, it felt like Gears of War with Transformers voiceovers, but that's not a bad thing in this case. It also gave a compelling backstory for the destruction of Cybertron, backed by superb voice acting. Seriously, the first time Optimus says "Autobots, roll out!", you'll be fighting back a little tear.
Try it, if only for the simple reason that it's the only good thing to come out of the Transformers franchise in the last ten years. Those of you who liked the movies and gobbled up all the CGI explosions supported by shitty one-liner dialogue, and cheered while my childhood was molested in front of me, go kill yourself. Do it now, and spare the rest of us from your idiocy.
