The Original Left 4 Dead maps and characters are now in the sequel. Not only that but you can get L4D bundled with L4D2 so just keep an eye out for when it goes on sale.
That being said, L4D is still a great Co-op zombie shooter. Characters are memorable, Bill will never be forgotten.
Quite a few maps to choose from and they are all great and tons of fun.

Great game with lots of great memories.
Be sure to get it in the bundle with L4D2
