Some new information about L4D2 to come out is the fact that it will be set in the daytime, instead of night like L4D1 and will feature new zombies.

The new zombies include brain eating fiends such as a "spitter" who sits back and spits inflicting damage around the point where it lands. The purpose of a spitter is to force your group to scatter and of course make it more challenging. Another new type of zombie is the "common-uncommons." These zombies are specific to the level you are currently running. In the Swamp level there are "mud men" who are fast, crawling zombies.

Also, GameSpot has reported that the pills and first aid kits will be taken out of the game altogether and replaced with ammo packs and adrenaline. It will be a sad day if we no longer are able to hear the characters yell "PILLS HERE!" Let's hope GameSpot is wrong! Otherwise who can't wait for this game! I know I can't!
