The zombies game was fun. It was a mod like I've never seen before. It gave you a set amount of time to find a hiding spot. After the intermission, it would pick 3 people at random and force them to switch teams. Every map had an eerie fog that made it hard to see, making it fair for the zombies. One person got to be the alpha zombie, giving them increased speed and health. Every time you died, you were forced to switch teams. The humans had 3 weapons, a randomly selected Submachine Gun, no attachments, randomly selected handgun, and randomly selected shotgun. Essentially, the best possible setup is UMP -> Magnum -> SPAS. I got it once and made it last alive. Zombies have a USP tac knife with no ammo, equipment, killstreaks or any means of killing someone outside of knifing. Zombies had thermal vision. You had the ability to buy things.
It had a point system. For every zombie you kill or get an assist, you earn 25 cash. Once that builds up, you have the ability to buy more ammo, an assault rifle, or a Riot Shield. The zombies had a similar system. For every death, you get 25. For every kill you got 100. You could buy a Thermal Enhancement that let you see exactly where everyone was, it used a red square. Zombies have Marathon -> Cold Blooded -> Commando to give them protection against killstreaks. Zombies could also buy a throwing knife, so your best bet against people that get into a good spot is to buy the throwing knife. It was TONS of fun and it even had it's own unique music playing. I had a great time.
I also met another youtuber in an SnD game, FaZe Clipz. After playing a few games, he added me as a friend. He's pretty good, got a 360 hitmarker on my friend Jeremy while he was on the other team which would have made it in his killcam episode.
