The inspiration this game takes from BioShock is apparent, and to the benefit of the atmosphere of Arkham asylum on the whole. The levels gradually open up in a very satisfying way as you add more gadgets to your arsenal. The main story even guides you back to previous areas once you have access to everything, giving the game a psudo-metroidvania feel. The scarecrow segments are highlights as well, shaking up the gameplay and injecting some horror into the mix. Unfortunately the boss fights feel like an afterthought, and the ending fight in particular is ridiculously simple. It's easy to see why so many games copied (and improved) this style of combat, but as the originator, Arkham Asylum remains surprisingly enjoyable to this day.
