Arena Tunel Help.. I am having a hard time pulling the engraving out of..

Ok. Once you reach the ladder, slide on it till you reach the end since you can only perform this stunt when you reach the end. You will notice you are at the very bottom of the ladder when you stop descending. Then chain your weapon to the block in order to hook it and remove it. You will do this by just pressing and holding the 'triangle button' . No need of pressing any direction button. Once the stone of block is hooked and removed (up to a certain length), you'll have to rush towards the door at the end of the hall (opposite the wall holding the ladder) since the stone block is the key to the door and once the block is released, it will slowly return to it's original position with the door closing simultaneously. TIP: since at this phase you are the evil pop and time is your life, you have to be quick to go pass the door and not repeat the whole proscess. Once you release the block, jump on it and then jump again onto the platform. Start rolling towards the door and do not stop rolling. It is actually faster than running.( it worked for me )
