Fast Zombie - 20 Damage, 60 HP, 1.4x normal speed, 0.60x normal gravity (Higher jumping).

Normal Zombie - 30 Damage, 130 HP, 1.2x normal speed.

The zombies have 5 classes to choose from, each with a different speed, health and damage. The script comes with 5 unique zombie skins, but if server owners want to disable them they can, and the script instead sets each player's colour according to their class (See the screenshots).

The zombies must then try to kill the remaining humans, and the humans must do everything they can to survive! Humans earn guns by killing zombies, and server owners can add their own custom guns, with custom names and damages (Detailed tutorial in the readme.txt) to be given to the humans when they kill a specified amount of zombies. This makes sure that the game does not end quickly because someone killed the first zombie. After he kills at-least one person, he is reverted to a normal zombie who has normal HP and does normal damage. He starts with extra speed and HP, and a one-hit kill knife. The game-play - When the round starts, a random human is chosen to be a zombie. It adds new game-play and tactics, as well as being very fun to play! Zombie Survival is a custom-made script for Counter-Strike Source.
