The story is very well adapeted and the game holds up, but some flaws damage the game experience.
The best part of the game is that you can choose sides and have a huge cast of characters. You can choose to be the Autobots and protect the earth, or you can choose to be the Decepticons, where your main objective is to undo the plans of the Autobots and destroy all. The transformations are just great. You can be a giant robot and, just by pressing a button, you’re a Camaro. All this happens in a fully destructible environment.
The bad part here is the havoc in the battles and the awful targeting. The graphic quality could be a little better and the sounds aren’t that bad, which makes this game acceptable.
There is a large set of bonus features (tough some are pretty boring to unlock) that can be unlocked as you complete the story. It will take about 30 hours, or so, to complete both sides. So this game can entertain you for a while. (If you want to complete the game to 100%, completing all extra missions and unlocking everything, then it should take about 40 hours).
You play the role of any Transformer (though you do not choose who and when, you just choose sides) and you just complete the missions that are given to you. The levels are divided in chapters (which are the missions), and a level usually has 3 to 4 chapters. Full Auto fans might enjoy this since there are going to be many car chasing missions where you dispose of nitro and weapons. There is a giant world you can explore while you are not doing a mission, full of other Transformers hidden ready to stop you and secret items that you need to have in order to unlock extra missions, and lots of other options, like climbing buildings and stuff. The actors are very well designed here (that’s because they only appear in cut scenes) and the story is great, and very well adapted to a video game.
So, in a short way, the PS3 version of Transformers is a good game (great for some) that takes some time for you to learn how to enjoy it. It is surprisingly better then what most people think. It is totally different from what it looks.
