Simply Amazing
I recently finished this game's main storyline but there is much more left if you want 100% and the achievements, a lot more. The riddles, side missions and combat maps will keep you playing this for many hours more. Great re-playability. The combat missions are fun and will get you better at the game. This is one of the more difficult achievements in a game to get though.
I really liked how they implemented Catwoman, not too much of her but just enough. The villains are extremely well done and just a great game to play. It would have been cool to see more of Robin, but maybe for the next one! I really hope they keep moving this series forward and continue to produce such great games.
If you like Batman at all, do yourself a favor and buy this game!
