Gameplay:

The two survivors/brothers work together to find four generators in order given by the main generator in the middle of the map. While the brothers are working to achieve this goal, the poltergiest tries to hunt the survivors down by immobilizing them from reaching their goal. Upon powering all generators, the area begins to illuminate, damaging the poltergiest, whose weakness is light. Powering generators requires light source from the player's flashlight, which in turn can be used to stun and defeat the poltergiest. Consequently, the survivors must do this while managing their battery power to protect themselves against the poltergeist.
