Single player story is really good, I think you have like 2 different ending in it (the fallowing dlc which is a must have if you already own the game). The story line is preety solid. The only thing I didn't like about it is the weapons, assault riffles and such, they are a bit off, nothing like I've played with before, but I got used to it after a short time and it didn't bother me that much later one. It is a game from 2015 after all. I think they are aware of the mechanism of their weapons alredy, so they won't implement the same thing in the new game, which they should release because Dying Light was their biggest project, and the most money eraning. So yeah get the Fallowing DLC with it because it's part of the game, it's preety huge, like another game basically.
