Counter-Strike GO will launch on Tuesday and players will also be able to enjoy the game's first mod, Zombie Mod from Plaguefest.com.

"It was important to us as we developed CS:GO to make sure it was as moddable and extensible as any CS game," explained a post on the CS: GO blog. "So this is just one of many mods that will be available to CS:GO in the coming months."

The mod will be available via Steam.
