It has decent gameplay, the gore mechanic is very cool and never gets old, the different weapons are also cool but it feels like they are missing a certain oomph. Otherwise, Dying Light did it much better and was a much more fun game. Also, ALL zombie games should take over L4D's feature of reloading having stages, so you don't have to start reloading again from the start cuz you're dodging constantly - which also feels a bit clunky sometimes.
Worst of all, DI2 doesn't even take place on an island!
