Having "Adventure" in the title is stretching the truth a little on the experience.
One reason is that you have to use the A button regularly, and I found it too cumbersome to change my hand's position to move from the trigger to holding down A to find cover. But, when you hold the controllers in a more traditional fashion, the controls work well.
The game-play itself is alright. The Autobot campaign gets very repetitive. You drive a little bit, shooting debris out of your way and Decepticons out of the sky. Then you transform, and shoot, take-cover, shoot, cover, shoot, cover, then drive, then shoot, then drive, then shoot, and the level is done.
The Decepticon campaign is a little more varied. At least on some of the driving missions there are moving barriers you'll have to avoid, as opposed to just debris in your way. There's more balance between flying and driving vehicles with the Decepticons, and during the shooting missions there's a couple spots where timing it important to shoot targets that are only exposed at specific moments. These little things helped to make it feel like you were doing something a little bit more than just driving and shooting. The one thing that was missing compared to the Autobot campaign was a boss fight at the end.
In general more boss fights like the one at the end of the Autobot campaign would have been appreciated. There's lots of other things I can think they could have done as well. Why not limit your weapons for a couple of levels? Change up the type of weapons that different Transformers have; throw in a lighting gun, or grenade launcher, or have a level where Optimus uses his blades instead of guns. Instead, every Transformer gets pretty much the same 4 guns for the entire game, and I found there was not a lot of reason to use anything other than the missile launcher. They should have put some more effort into the possibilities with an on-rails shooter like this.
The game is rated T. From a difficulty perspective it makes sense, because some of the missions can get a little more challenging, particularly the ones with time limits. Some younger, less seasoned players may have too much trouble with these parts, if they're not regular players. The style of game-play itself on the other hand seemed like it would be appreciated more by players with a less sophisticated gaming palette and would simply enjoy seeing Transformers on the screen as opposed to yearning for a title with variety and depth.
The multi-player aspect was a little disappointing as well. It may work at best as an okay title for a father-son-like experience (which is what I was hoping for), but Player 2 may feel a little short-changed. The second player only gets their choice of 2 weapons (not four), and they serve as some mystery Transformer that never appears on screen. The only reason this makes some sense is because in the driving missions, one of you fires missiles while the other drives.
It's not a bad game, in the sense that everything works, it looks acceptable, and there is a lot of action with a few genuinely engaging moments. However the repetitive nature of the levels does provide the feeling that there was a lack of effort to try and make a great game. It's just a play-it-and-forget-it game with only a niche audience that would enjoy it.
