There's a quick turn button so that you can turn 180 in a heartbeat should allievate some of the attacks from behind.
And the whole limited ammo thing has been a staple of the series, what I tend to do is like shoot a person in a limb or something and hope you get a knockback attack. My beef with that of course is the fact that they don't always pop-up so you go in close and still get hurt.
and you can also use your environment to your advantage. In the Shanty Town one, the first room, you can blockade both doors with the bookshelves to slow the rate of the infected and try and pick them off as they come in.
Once the axe dude enters, it opens up the rest of area and tons of explosive barrells for you to use.
I don't know, myself and Magus enjoy the game a fair bit and will hopefully beat in co-op if he can keep himself from getting beheaded and smashed.
