Left 4 Dead DLC's are an experience

So, I'm up at Hamburg visiting my grandma, and while I'm here I decided to visit my cousins too. I let my cousin borrow and play my L4D2 disc, and he has ALL of the DLCs. Pretty sure he bought them when we were little and had an Xbox 360 or One.. Easy to say I'm definitely jealous lol. Anyway! We played some DLC's while I was there. We played The Passing and Cold Stream while I was there, and oh boy, it sure was something!
The Passing was pretty simple apart from us just.. Not knowing where to go half the time. And Cold Stream? My God... It was a lot. We didn't even make it past the 2nd chapter! And along with that horrible campaign, we also turned on DOUBLE SPECIAL INFECTED. So almost every few seconds there were 2 hunters, 3 spitters, 2 chargers, ETC... It was nuts. 

When I visit there again, I'm definitely going to try to play Crash Course and The Sacrifice, even though it'll 100% be a train wreck. Can't wait!
