You stole my strategy lol. JK this is exactly what I do. I open all the areas in the light house though. That way more zombies head towards me and I rack up points way too easily.I can do it with any Assault Rifles or Machine Guns
running circle loops in front of the Lighthouse wont get you trapped. That's only if you've got more players in that spot tryna do the exact same thing as you.
But the problem is if those players don't know what the hell there doing then your whole entire team is screwed. Because the zombies will just go in separate directions according to whoever is closest to them and eventually corner you. So word of advice. if you wanna survive long and make it on the leaderboards with your friends. Have everyone pick there own spot that they feel comfortable in and stay their until the round's about to end or if you have a crawler. And i don't recommend playing with randoms either. Bad experiences i have with stupid asses that think it's funny to piss off George for no apparent reason other then to freeze up your speed movement that gets you killed.
