Usable petrol canisters

Some canisters could be placed in random locations of maps, but as well as being able to shoot them to create a fire we can pick them up and choose to unscrew the cap, pour petrol anywhere we want or along in a line where it can be ignited to cause a temporary wall of fire.



These could be used as a last effort to survive if all team members have died, since a lone survivor is likely to run away from the horde.. more chance of finding a canister. They could also be used to refuel a chainsaw, if one is in the game.
