Just wanted to let you guys know that you can jump off the lighthouse without using the zipline. Basically me and my friends were playing a game of Call of the Dead. We were doing a strategy that involved rappeling off of the Lighthouse. Unfortunately one of my friends fell off the top of the lighthouse and got downed.

I didn't have perks either, but had an idea - there was a rock / cliff like thing on the right side of the Lighthouse. I jumped off the lighthouse and basically slid down the rock and landed unharmed at the bottom, where I revived him.

Pretty cool, right? =P.
