The versus mode is the weaknesses. Few bugs to be fixed as usual. Story mode is just like the classic left 4 dead play style with a new spin adding perk cards and random bonuses to be found throughout the levels. Leaves me wondering why the hell they changed the versus mode. Main reason I bought the game was the pvp.....Sorry to say not worth the 11 YEARS of waiting! Fix the versus mode and you have 5 star game. There's a solid foundation here to work with. Just needs polished up.
Oh yeah if you haven't played left 4 dead 1 or 2 your missing out and you would understand why us old farts are so let down.
