Left Behind: Tribulation Forces

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.

Eternal Forces received "unfavorable" reviews according to the review aggregation website Metacritic.

Though some reviewers praised the game for originality, many panned it claiming it had a ridiculous plot, mediocre gameplay, poor graphics and sound, and technical problems with the user interface, pathfinding, and A.I. In addition, many reviews criticized the game for allegedly promoting sexism, bigotry, and religious warfare, and the option to play on the side of the Antichrist in a Christian video game.
