The single-player story is arranged in 15 chapters, which players complete in order to progress through the story. The game is played from a third-person perspective in which scavenging for supplies and learning when to fight or run are key to surviving the dangers of the game.[2] Such dangers include: bear traps, barbed wire traps, bombs, and spike traps; 'The Haunted', the game's most common enemy; 'Reborn Laura', a multi limbed, long haired, crawling creature; Ruvik, the game's main antagonist; 'The Keeper', a large humanoid with a safe as a head who wields a large meat tenderizer hammer; and 'Sadist', a large humanoid wearing a spiked metal mask on his face, wielding a chainsaw covered in blood.[3][4]
Sebastian Castellanos, the protagonist, needs to make use of the environment and things he may find in order to survive. The game world can transform during scripted events and as a result of player actions, altering locations and creating new paths or teleporting the player to new areas. Sebastian can find and use Syringes and Medical Kits to heal himself when injured. The Medical Kit expands Sebastian's health, but causes hallucinations to occur for a short time. Collecting vials of 'Green Gel' hidden throughout the game, players can upgrade Castellanos' abilities; more ammunition, extra stamina, and additional health are some of the upgrades.[5]
