Gasoline and Black Zone

[MattyB667]

Hey now. Just bought the game couple days ago and it was a blast. But a couple questions on the game.

1) Im not sure on the rule of the black zone zombie hero thing. It says if the track is in the black zone and a hero is killed it becomes a zombie hero. But what if it is in the red zone? Does it not become a zombie hero after?

2) So to make sure does the zombies win when 4 heroes are killed? So can one player respawn 3 more heroes 2 players spawn another?

3) How does the gasoline work exactly? How do you fill the truck with it, and how could you use it as a weapon (ranged or using it to kill yourself to kill zombies)

Thank you for reading!
