Story
Batman: Arkham Asylum features an original story penned exclusively for the game by famous Batman author and five-time Emmy award winner, Paul Dini, whose credits include "Lost" season one and "Batman: The Animated Series." As the game begins Batman is personally delivering his nemesis, The Joker, to the asylum at Arkham Island, but he is uneasy. Although the Arkham asylum is well fortified, he has a nagging feeling that all is not well, which proves to be the case when seconds after turning The Joker over to the guards, the master criminal breaks free of his captors. Even more surprising than this quick turn of events is the revelation that it was never The Joker's intent to escape the vault-like facility, but instead to trap Batman there. Surrounded by an asylum full of dangerous criminals, many of which he put there and all at the beck and call of the Joker, can Batman survive and discover what is behind the Joker's intricate plot?

Gameplay
In Batman: Arkham Asylum players strap on the gadget-heavy utility belt of the Caped Crusader. Gameplay here is a combination of both the knuckle crunching rush of hand to hand combat as you take on the hordes of thugs that infest Arkham Asylum, and stealth gameplay in which you must dispatch individuals from the shadows. Players can expect an engrossing single player campaign in which Batman continually moves forward to face the henchmen, bosses and traps that The Joker has set for him. With regards to opponents, in addition to The Joker who you will hear more than you see, the dark walls of Arkham also hold familiar villains from the the Batman criminal universe including Harley Quinn, Victor Zsasz and Killer Croc, that you will have to deal with, but don't expect a one-dimensional experience. As players progress from environment to environment within Arkham they will have to use varying combinations of muscle, detective skills, gadgetry and a certain degree of light RPG-like leveling of Batman's skills, arsenal and physical characteristics to survive and discover what The Joker's underlying scheme is.

In addition to the story-driven single player campaign Arkham Asylum also contains various additional play modes. These include an arcade styled combat mode where players accumulate points by engaging hordes of thugs in a hand to hand slugfest across a series of maps, in which Batman's physical strength and agility play a major role. The key here is to chain together as many attacks as possible due to the fact that with each successful combo players increase the point multiplier associated with their actions. The game also features a time-based stealth mode where players must hone their ability to strike silently from the shadows. This gameplay, referred to as 'Invisible Predator' utilizes the Dark Knight's skill with gadgets like the grapple tool, batarang and explosives. These allow for vertical/horizontal mobility, the ability to quickly strike from above and at a distance and to take out enemies and create distractions, even through walls. But remember that Batman works solo and is not superhuman. Your enemies will congregate around trouble areas and work as a team against you, so you must be silent, plan your attacks wisely, strike quickly and discover the value of encouraging fear within enemies.
