Don't think that because this is a 4 player co-op game, you can't play it alone. The A.I. players often play better than other people in the sense that if you're hurt, they'll go out of their way to defend you when an infected captures you, or bring you a medkit or patch you up when you're low on health. If you love fps's and haven't played l4d, you're missing out on a great experience! Even if you're not into zombies, there's great gameplay to be had and a variety of weapons to take down opponents in gloriously gibby ways! Give it a try, you'll be glad you did!
