WATCH THE BIRDIE!
Distract zombies to complete an objective.
State of Decay YOSE – WATCH THE BIRDIE Achievement Guide
This achievement can be done early on in the game during the “Rescue Lily’s Brother” Mission. When you arrive at the barn you can run the zombies over with your car. After the cutscene you will get a few firecrackers and are told to make a distraction.
Go to the blue marker outside, throw the firecrackers and the achievement for completing an objective by distracting zombies will pop.
