What else can I say?
+ Easy to start off if you know what to do, you may die a few times, but it's worth it, because in the end, you'd have good stuff and basically "beat the game" in 2 weeks.
+ Smaller map, and if you spent your time on this game, you can basically memorize it. If not, find yourself a map at the airport.
+The graphics are... meh. Not the worst, but not the best. If you want good graphics, you have to suffer from lag.
+ Zombies are a joke if you spent your time on timing your hits and backpedaling.
+ If you "beat the game" for the 2.0 version, this version is a joke. You get everything you need fast, but in 1 hour instead of 2 weeks. That's how easy it is.
+ Zombies are much harder to kill due to the nerf on most weapons (Sledgehammer used to OHKO any zombie in the head, now its not), and they have longer attacking animations, so you have to practice fighting all over again.
+ MUCH BIGGER MAP AND GREAT IMPROVEMENT ON GRAPHICS, HOLY JARATE. (TF2 reference, don't judge)
+ Random cheat sheet when you open your menu and going into info, you can find yourself the whole f*cking map. Screw 2.0 PEI maps.
+ MOAR GUNS, EVEN MOTHER OF RUSSIA JOINED THIS WARFARE.
+ Zombies are stupid, they don't chase you out of the town.
+ Apparently Nelson plays TF2 as well, if you know what I mean, that means you found the secret item :)
Overall, excellent game, but too easy for anyone that has common sense, 10/10 will play agian xD
