Dying Light has released a development diary that details the game’s freerunning elements, or “Natural Movement,” as developer Techland calls it.

Producer Tymon Smektała said that when the team started development on Dying Light they looked at other first-person games and felt that they lacked the ability to let the player move freely and seamlessly.

Lead Game Designer Maciej Binkowski said that, at first, they tried placing special objects in the environment that would allow the player to climb up various structures. When 50,000 objects still weren’t enough, they realized that they’ll have to find a different solution. Dying Light’s Natural Movement, as you can see in the video above, allows you to climb almost everything you see in the game, with smooth animations reminiscent of DICE’s Mirror’s Edge.

Techland believes that its Natural Movement is a significant evolution in first-person games. Game Programmer Bartosz Kulon said that it might take you five or six hours to master it, but that once you do, it will feel like second nature.

Dying Light launches in February 2015 for Xbox 360, Xbox One, PlayStation 3, PlayStation 4, and PC. Developed by Polish studio Techland (Call of Juarez, Dead Island), the game was originally expected to launch this fall, but was delayed in May so the developer could improve Natural Movement.
