Operation Flashpoint: Col War Crisis, sometimes shortened to Operation Flashpoint, and abbreviated OFP, is a tactical shooter and battlefield simulator video game developed by Bohemia Interactive Studio and published by Codemasters. It was released on June 22, 2001 in Europe and August 30, 2001 in North America. Set on a group of fictitious islands in 1985, Operation Flashpoint puts the player on one of three sides in a hypothetical conflict between NATO and Soviet forces. The Resistance is the third playable faction. Two expansion packs were released; Gold Upgrade, which included Red Hammer, a campaign from the Soviet perspective, and Resistance, which introduced various new features and improved graphics and sound effects. Operation Flashpoint was praised for its attention to realistic combat.
