Zombi

For some reason, your helicopter runs out of fuel, so you land on the roof of a zombie-infested shopping mall. What do you do? Call the Hell's Angels for help, of course. But help won't arrive until you block all the entrances with the three trucks outside, kill all the zombies inside the mall, and dump their corpses in the basement freezer (not sure whether it's all or just a certain number of corpses). Only then will the Hell's Angels show up. But for some (never explained) reason, they turn against you.

Now you have to kill them, steal the fuel from their van, and use it to refuel your helicopter with it so you can escape.

Do vans and helicopters even use the same fuel?
