Can I get it by killing a bottle of acid and dismantling a car in seven days?

Yes. "7 Days to Die" is a new open world zombie game developed by The Fun Pimps Entertainment that combines first-person shooting, survival horror, tower defense and role-playing elements. A bottle of acid is a prop in the game. It has a corrosive effect and cannot be obtained through crafting. It can only be found by dismantling abandoned cars and garbage piles on the road.
