Bird Simulator is a crazy game in which you control the descendants of dinosaurs. The only chance to get back to the top of the food chain is to destroy humanity.
Start in a small town where you try to destroy literally everything, like people, cars or other birds. Indeed, you will have plenty of destruction options; in addition to using your own feces, you can also use other items such as a chair or a grenade. You can also carry things, including people.
If you expect a serious game, you better buy something else. This is pure bird madness.
