How do I shoot?

PrivateJoker

Ok so I went back to the future and I'm trying to make Marty shoot at the clones. What gives?

This isn't a shooter, so you have to go a more roundabout way.

Here what you have to do:

Take the batteries out of the fridge.
Use batteries with BFG9000.
Use BFG9000 with broken staircase.
Look at debris.
Pick up Petrol.
Use petrol with chainsaw.
Use chainsaw with zombies.
