About how many missions are in l4d (left 4 dead)? And are those missions usally hard? And do u recommend the game?

There are 4 campains and each campain has about 5 missions. As for difficulty, you can choose easy, normal, hard, expert, ect. I recommend this game if you're really into multiplayer, because multiplayer is a blast. But it does tend to get a little boring if you're just playing by yourself.
