Batman: Arkham Asylum is an action-adventure game viewed from the third-person perspective. The playable character is visible on the screen and the camera can be freely rotated around him. The player controls Batman as he traverses Arkham Asylum, a secure facility for the criminally insane located off the coast of Gotham City. The opening areas of the game are linear, serving as a tutorial for the moves and approaches available to the player. Once the player emerges onto the island they can freely explore the game world, although some areas remain inaccessible until certain milestones in the main story. Batman can run, jump, climb, crouch, glide from heights using his cape, and use his grapple gun to climb low structures or escape to higher ledges.
