If you were ever worried about getting the most bang for your buck with the upcoming open-world survival horror game Dying Light, this bit of news should put those worries to rest. According to a statement from the game’s producer, Tymon Smektala, in order to wring every ounce of content from its big, zombie-infested world, you’d have to spend in excess of 50 hours.

“The game is absolutely huge as it is, but to provide the ultimate zombie survival experience, we added an extra element of unpredictability to our nighttime gameplay,” says Smektala. “Online players can face the threat of a possible invasion of their game by the Night Hunter, an extremely powerful, human-controlled zombie mutation. These invasions are an inherent part of Dying Light, available on all platforms for all online players from day one.”
