Much, Much harder then the last one. This game has a plot, which makes you feel that you have something to fight for! Much less companions, the barriers are weaker. But they added new weapons such as the compound bow, which sucks. Also the chance of finding anything is lower, which in a real zombie apocalypse, should be appropriate. 5 Stars completely! They still don't have a difficulty level though. :( It still was a little easy.
Tips:
Shotguns are good.
Rifles are better
Automatic are for companions
Bows are trash
Chainsaw for big groups.
