tip: you can get easily overpowered from putting LOTSA points into blades and then going for achievments straight up, infact doing a speedrun will get you most achieves, while others will require you to do something with lots of zombies like shove back 50 (or 40) zombies, best way is to shove back a horde and let a partner (if you didnt kill them) kill the enemies with a severley overpowered and fun GUN, dont give them ANY type of mellee, not even a chainsaw or they wil GUNTEEDIOUSLY die.
also id like if stats transfered to items in the enviroment aswell: your weight doesnt cope with the boxes weight, meaning if you are at max weight and the storage units at max weight your f)cked since apparently storage isnt upgraded, still this was WAY better than ast stands previous versions were you just sit at a blockade waiting to basically die since you had no will for exploration and your wep.'s were crap, this actually adds a feeling of a true MMO in single player. 6/10.
glitch with the horde: going inside a safehouse right after horde music occurs cuases the music to loop annd zombies can appear in the safehouse, NPC's will cry help as if the safe house is just another building.
