The chainsaw is slightly less powerful than the rock drill and has different types of attacks, but is slow to recover and rather difficult to use. Unlike the rock drill, however, the chainsaw can be turned on and used to attack enemies while Harry is moving, allowing him to deal damage by simply walking into enemies.
Silent Hill: Homecoming
The gasoline tank, known here as the Gas Can, is meant to hold enough gas to power the sump pump in the Shepherd family's basement. Alex Shepherd can find it in the Shepherd family garage, in a locked box, which Alex must pry open with his steel pipe and take. Alex then siphons some fuel out of the tank of a crashed truck and return home and power up the sump pump, draining the flooded basement. This allows Alex access to the back of the Shepherd House.
