I'll tell you the story of Zombie 2 and Zombie 3. One day, two friends were doing well. When the virus arrived, they hid in the house. So many zombies arrived at the third zombie's house. Coming soon.
When he was on the pole in pain, the zombies injected him. He had another friend, and he survived, but his other unconscious friend killed him and is now dragging him away.
In the house of the third zombie (ex-human) he shot himself out of fear but they just injected him, that's why he has blood on one arm, the third zombie (human) was put on a stick, coming soon.
