Left Behind: Eternal Forces is a Christian real-time strategy game developed and published by Inspired Media Entertainment (formerly Left Behind Games) for Microsoft Windows. It was released on November 7, 2006. The game is based on the evangelical Christian Left Behind series of novels. Gameplay The game features a single-player campaign and an online multiplayer mode. In the single-player campaign, the player controls the Tribulation Force, a Christian group in a post-Rapture New York City, who are combating the influence of the Global Community Peacekeepers, the world government led by the Antichrist Nicolae Carpathia. The player directs the actions of the main characters (Rayford Steele, Cameron "Buck" Williams, Chloe Steele, and Bruce Barnes) and the Tribulation Force's units in an effort to defeat the Global Community Peacekeepers by converting neutral and Global Community-allied civilians to their side and only using lethal force against the Antichrist's army forces when necessary. But the player's main goal is to use conversion rather than violence, only resorting to combat when necessary, since killing causes the "spirit level" of the player's units to drop. If the "spirit level" of a player's unit drops too low, the unit will turn neutral or defect to the GCP (Global Community Peacekeepers), which can cause the player to lose the game. In the multiplayer component of the game, up to eight players can compete online against each other in teams, with one team playing as the Tribulation Force and the other playing as the Global Community Peacekeepers. Development The game cost between $3 million to $5 million to produce. Sequels In December 2006, Left Behind Games announced an expansion pack for the original game, which was scheduled to be released on November 15, 2007. GameSpot news reported in an interview with CEO Troy Lyndon that Inspired Media Entertainment had signed a deal with Big Huge Games, creator of Rise of Nations (2003) and its spin-offs, in order to use the Rise of Nations engine to produce a sequel to Eternal Forces instead, titled Left Behind: Tribulation Forces. That sequel was released in April 2008, and features new graphical building enhancements, a new neutral faction (the American Militia Forces), five new missions, and two new maps. In May 2008, a version 1.05 update was released. Left Behind 3: Rise of the Antichrist was released on October 25, 2010. Left Behind 4: World at War was released in November 2011. Reception
