Zombies.
Nuff said.
Actually you probably know me well enough to know I'll have more to say here. So let's start with a picture. The sim is full of places you can snuggle up to a .50 cal or 12 gauge and hang with your friends. Seriously, Forgotten Souls is like one "horror" room after another.
I should warn you that there's lots of adult situations there, zombies have sex too I guess. If you're comfortable with some zombies doing it, some caged people and stripper poles, a Sybian machine and lots of drug stuff here and there, you'll love it, especially if you like to take pics.
Forgotten Souls has a LOT of stuff going on. We explored a church, the first floor of a couple buildings, a hilltop area with multiple places for great pics, a wrecked ship and the aforementioned graveyard. My loyal traveling companion agreed we need to go back. It's that much fun.
