Operation Flashpoint: Resistance

The gameplay is the same as the original game. It varies significantly depending on the player's role, but the game is best described as a tactical shooter with significant vehicle elements and minor real-time tactics elements. OFP 's gameplay is largely team oriented and the player spends much of the game with a squad of up to 11 AI controlled members, either as a member of the squad or as its leader. On-foot gameplay and the vehicle elements are blended seamlessly and the player can get into any available vehicle at any time, orders and mission conditions permitting.

Whether on foot or in a vehicle the player can view the action from both first and third-person views, as well as an additional 'command view' available to squad leaders which gives the player a limited birds-eye view of the surrounding area. At the start of each mission the player is presented with a briefing explaining the situation, describing the player's goals in the mission and, often, providing further information in the form of notes. Once in-game the player is provided with a map, compass, watch, and a notebook. Depending on the mission the player may be required to participate in and complete a variety of tasks, from simply driving a truck or guarding bases to attacking or defending various objectives, patrols, reconnaissance and sabotage behind enemy lines, air support, or any combination of these and more.

In 1982, Victor "Viking Viki" Troska (voiced by Stephen Critchlow), is an ex-special operations soldier who has returned to his homeland of Nogova after years in exile serving with British special forces. Nogova is a small and quaint island nation whose coalition government has recently collapsed. The island is then invaded by the Soviet Union after some members of the Nogovan Communist Party betray the country and invite Soviet forces to overthrow the government and install a socialist puppet regime. Troska is approached by Nogovans who are resisting the Soviet occupation and asked to join them.

Initially, Troska refuses to have any part in the fighting and rebukes them because he wants to put combat behind him and also he believes that any resistance will be futile and the inexperience of the partisans will get them killed. Later, a wounded guerrilla fighter being pursued by Soviet soldiers takes refuge in Troska's shed. When Soviet soldiers, led by Colonel Guba, arrive and threaten to shoot Troska and his friends if they do not co-operate, Troska is forced to make a decision: betraying the partisan, trying to negotiate with the Soviets or fighting off the Soviet soldiers and joining the resistance.

Bohemia Interactive released Operation Flashpoint: Cold War Crisis in 2001; the game was a huge success for the company. Bohemia Interactive supported the game by releasing new addons and patches but eventually decided that they should make "something bigger." They started to work on a new expansion called Operation Flashpoint: Outrage. This expansion was meant primarily for Central and Eastern Europe, while Codemasters, publisher of the game, worked on Operation Flashpoint: Red Hammer, which was meant to release overseas.

Outrage was later renamed to Resistance as Codemasters disliked the name. Resistance was officially announced in February 2002 and released on 28 June 2002 in North America and Europe, and on 16 July in Australia. It received positive acclaim from players and critics alike. A dedicated server for Linux was made available on 21 March 2003.

Resistance was released to very positive reviews. It was praised for its story and the whole idea of guerrilla warfare as well as for its missions and technical improvements but it was also criticised by some reviews. Technical improvements are according to some critics unnoticeable and missions were criticised for less variety than the original game. GameSpot named it a runner-up for its July 2002 "PC Game of the Month" award.

ActionTrip released a review that praised the guerilla warfare and extra content. On the other hand, it noted the dated engine and dodgy AI.
