I'd give it a 5 out of 5, because you can learn new things about the game you did not know and the campaigns are awesome! Although the bots are really stupid. one time I was being smoked to death and coach just standed there and did nothing. Also just please release left 4 dead 3. Oh and don't even get me started with the bad people on there, some of them just don't care about other people and only their selves and some of them grief of course, it really gets on your nerves when your trying to get an achievement and they just grief and mess it up for you.
