Evolve is a first-person shooter video game developed by Turtle Rock Studios, published by 2K Games and distributed by Take-Two Interactive. Announced on January 7, 2014 and originally set to be released in late 2014, the game was delayed and released for Microsoft Windows, PlayStation 4, and Xbox One on February 10, 2015 worldwide.Evolve uses an asymmetrical structure where five players, four playing as hunters and one as the monster, battle against each other in an industrialized alien planet called Shear. The hunters' gameplay is based on the first-person shooter design, while the monsters are controlled from a third-person perspective. The hunters' goal is to eliminate the monster, while the monster's goal is to consume wildlife and evolve to make themselves stronger. The game can be played alone or with multiple players.Evolve was Turtle Rock Studios' first major project after the company split from Valve Corporation in 2011. The concept for Evolve existed prior to the development of their previous game, Left 4 Dead. Inspired by hunting games such as Cabela's Big Game Hunter and Deer Hunter, the idea is to have prey that can strike back at the hunters. The monster design was originally intended to be esoteric, but was later toned down. The game is powered by Crytek's CryEngine to create the dark and dense forests in the game. Turtle Rock Studios found difficulty when seeking publishers that could provide funding and marketing for the game. THQ was originally set to serve as the game's publisher, but the rights to the franchise and publishing duties were transferred to Take-Two Interactive after THQ filed for bankruptcy in late 2012.
