Story is good and has some great humour in it and the co-op makes it all that much better.
They have made it easier by getting rid of some of the time restrictions which made 2 a bit annoying.
Only problem i'm finding is that it would benefit from having a waypoint (like in GTA V) as it can be a bit difficult (for people like me) to find their way to the different side missions.
But loving the weapons, combining diff things to make super weapons is alot easier in this one too.
Did the 'Kill 5000 zombies' cheevo the other night. That was ALOT of fun!
Wasn't sure about the Xbox One at first but damm it is so worth getting it just for this game! Plus it's a pretty cool console, very slick.
