Batman: Arkham City


 * 1) Navigate to  Steam\steamapps\common\Batman2\BmGame\Movies
 * 2) Rename bac_logo.usm for the logo, startup.swf for the DC/Rocksteady intro, and startupnv.swf for the nVidia intro. This will cause them to not be recognized by the game, and will not be played.
 * 3) Enjoy.
 * 4) If you want them back, rename them to their original name.
