As one last resort to keep you out of Frank's memories, he sends a deadly spider after you to do battle with you on the lake walk. This is rather hard for this game. You probably won't beat it on the first try. If you are bitten, then you will be transported back to the church's driveway. This get's old and redundant, but stick with it. The best way to win this battle is to memorize, slowly, the gesture pattern for the first attack. Then once you have that down you must kill it in the first attack, don't let it push you back. (I spent a 10 minute battle with it once going from the last attack to the third and the second, back and forth.) You will enventuraly beat it. Just stick with it and don't give up, because it might take you 10 or 20 times to get it.
