From my point of view this is basically L4D with RPG elements and better melee fight viability.

+looks great
+feels great to smash monsters with hammer over their head
+unique characters with very different playstyle
-veteran items are quite rare
-after you reach lvl 30 and power 300 items it becomes repetitive
-time by time you encounter annoying bug
-I HATE THERE IS NO OPTION TO PAUSE SINGLE PLAYER AT ALL!!! Does not make any sense to me. Seriously my bots can wait for me...

Worth it? Definitely.
