The green and ghostly hens of Counter-Strike

Valve has made some spooky Halloween changes to its combat shooter Counter-Strike: Global Offensive.

The game famously features clucking chickens, mooching around and waiting to be shot, doing no harm. In the Halloween update, dead chickens are resurrected, in chilling green hues.

Characters in the game have been given masks, taken from Payday 2 and Team Fortress 2. Also, fallen comrades inhabit the game as ghosts.

On the subject of chickens, a Valve blog post noted that "for too long the chickens of CS:GO have idly watched as their brethren were slaughtered by the droves, and on All Hollow's Eve there is no more room in Chicken Hell."
