I have a PC while using the XBox controller. Getting used to the fixed camera, yet I am stuck while trying to climb up the spears. Do I turn off the PS3 controlls, then just use the keyboard to climb the spears? Seems that I can't climb up to spear. Used the grappling hook, went into the wall, then came right back out. Is this one of those games where you have to switch between keyboard/joystick?
