Batman AA is an incredibly dark and sinister action/adventure game that puts you in the notorious prison: Arkham Asylum
-The batarang which the name explains by it self.
-The explosive gel that... well.... explodes.
-The grappeling hook which will be the most used of all.
With these gadgets you can do the most amazing and diverse monstrosities to your enemies. The story managed to keep me awake for about 20 hours, after that it should take a few more hours of searching to complete the riddles. There is a challenging... challenge mode, that allows you to train-- more like demonstrate-- your skills in combat and stealth. The amosphere is one of the darkest you will ever see in a video game, it might even keep you awake if your afraid of the dark (not me ofcourse :P). With all it's might it truly deserves a great big 9.
