I can't figure out how to do the running slide thing, what buttons do I need to press to pull off this maneuver. I cannot beleive the instruction manual is none existent for this game. And there is nowhere online that has a simple explanation of these controls to pull this off.
You don't need an instruction manual, go into the Waynetech menu for the Batsuit. It gives you a description of and just about every way to use every single move Batman has available. --- "Anywhere is within walking distance, as long as you have the time."

For the record pressing select and cycling over the combat menu will list all or your available moves, including the slide, and selecting them will tell you how to use them. You also have a screen for gadgets. --- Bane even prayed for Dick when he became Batman. -- Frostbite_Zero
