There is not much to like about this game. The graphics are quite blocky/choppy. The hit detection is spotty. The vehicle control is awful. Every Autobot controls exactly the same way and there are no power ups or upgrades so the game plays exactly the same at the end as it did the beginning. The story is contrived with part about a new Transformer quite interesting, but 80% of the game has to do with finding the kids and rescuing them after they tried to rescue a 100 ton robot. Can't say I approve of the Autobot's parenting or babysitting skills.
Anyway, there are 3 types of enemies - a big one, a small one and a flying one and you fight them until you get to a boss, which sometimes is actually at the beginning of the level. These fights are probably the best part of the game, but are over much too fast. Skip this one.
