I started playing Batman Arkham Asylum again because I got Arkham city as part of a Humble Bundle. I figured I needed to finish the first before playing the second. Because of this I made a profile to use my Logitech G13. I tried to use my Logitech gaming pad and it was going to be a pain in the butt because the game is setup for an XBOX 360 controller. Someday I might just switch to one of those. The profile is very simple, there aren’t a lot of buttons in Batman. Below is a screen shot of the keyboard layout. I put grapple on my mouse 5th button. You might have to modify the profile to point to your install of batman because I installed it on my D drive for Steam and not the C drive because my C drive is a SSD that is pretty loaded up.
