The Left For Dead 1 Game Update, gave you that Car Pile-Up Achievement for free etc...

I ended up unlocking this achievement also before buying the DLC.

i love the game but the 1st has more playes still playing but the second has more modes but deos not to seem to have lots of players hope when i get the 2nds dlc it would as the add ons are near the top of x boxs most downloaded lists

If you recovered your account over your friends house and played it with him, earning an achievement, you will get the acheivement as well.

It happened to me a while ago. It's a glitch.
