Goat of Duty is a video game created by the rather niche 34BigThings studio. The game is, in its core, a rather default online shooter with normal mechanics. Humour is what it makes up its normalcy with: player controls a goat, and is assaulted by a seemingly unlimited amount of proper puns.
Guns, power-ups, third goat perspective: if you are interesed, Goat of Duty is currently available for free on Steam. Offer stands until the end of March.
