World in Conflict is a 2007 real-time strategy (RTS) video game developed by the Swedish video game company Massive Entertainment and published by Vivendi Games for Microsoft Windows. The game was released in September 2007, receiving generally favorable reviews and several awards. The game is considered by some to be the spiritual successor of "Ground Control", another game by Massive Entertainment, and is generally conceived by its designers to be a real-time tactical game, despite being marketed as a RTS game.
