Tango Gameworks’ survival horror game “The Evil Within” was released this week on PC, Xbox One, Xbox 360, PlayStation 3 and PlayStation 4. The terrifying title, which was revealed by Bethesda Softworks in 2013, has been well-received by a number of critics, earning a score of 84/100 on Metacritic.

Before players lose endless hours on the third-person title, here are five interesting facts about the game, which took four years to develop.

1. In Japan, “The Evil Within” is called “Psycho Break.” For the Japanese version of the game, developers had to remove gore-related content to receive a D-content rating, allowing the game to be sold to players over the age of 17 to avoid limiting its audience. Japanese players have to download the Gore Mode DLC to play the full, uncensored version of the game.

2. “Hell on Wheels” actor Anson Mount, 41, provides the voice for main character Sebastian Castellanos. “Dexter” actress Jennifer Carpenter, 34, voices one of the main protagonist’s colleagues, Julie “Kid” Kidman.

3. Development on the game began in 2010 under the codename “Project Zwei.” The process originally began at Tango Gameworks, and the studio was purchased by Bethesda Softworks in 2010, shortly after development began. This will be Tango's first exclusive title.

4. The game was directed by “Resident Evil” franchise director Shinji Mikami, 49. The original “Resident Evil,” which launched for the Sony PlayStation in 1996, set the precedent for future horror games, and became well-known for bringing the genre into the mainstream. At the time, the game’s success was partially responsible for help Sony’s original PlayStation become the dominant game console.

5. The design of the game intentionally attempts to make players feel claustrophobic and powerless by taking place in small spaces, limiting weaponry and forcing opponents to face nearly invincible enemies.

6. The in-game asylum was modeled after the Winchester Mystery House in California, an odd mansion built by Sarah Winchester, the widow of William Winchester, a gun magnate and treasurer of the Winchester Repeating Arms Company. After her husband’s death in 1881, Sarah was left with a great deal of money and used it to continue construction on a seven story mansion in San Jose, California, a request she believed was being placed upon her by the spirits of those killed by Winchester rifles.
