Medal of Honor was released on November 11, 1999 on the PlayStation, developed by DreamWorks Interactive and published by Electronic Arts. The story was written by Steven Spielberg and Medal of Honor was a huge success often regarded as the best first-person shooter on the PlayStation. Medal of Honor: Underground was released the next year and was the first World War II game to allow players to play as a woman. The next instalment, Medal of Honor: Allied Assault, was released in January 2002. Allied Assault was the first Medal of Honor to be released on Windows. Allied Assault was also developed by 2015, Inc., instead of DreamWorks Interactive. Medal of Honor: Frontline was released later that year and development was taken over by internal studios within Electronic Arts. Frontline was also the first multi-platform Medal of Honor title, being released for the PlayStation 2, GameCube and Xbox.
Medal of Honor: Rising Sun was released in 2003, which was largely similar to Frontline but took place in the Pacific battlefield. Two expansions for Medal of Honor: Allied Assault were released shortly after Rising Sun. Spearhead was the first expansion and added new battles to the single player. The next expansion, Breakthrough, did the same but was developed by TKO Software. After Spearhead and Breakthrough, Medal of Honor: Infiltrator was released for the Game Boy Advance and was developed by Netherock. Infiltrator was the first Medal of Honor released for portable systems. Medal of Honor: Pacific Assault was released in 2004 as another PC exclusive instalment. The single player was once again developed by EA's internal studios while the multiplayer was developed by Breakthrough developers, TKO Software. Medal of Honor: European Assault was another multi-platform release for the series and was written by Apocalypse Now writer, John Milius instead of Steven Spielberg. In 2006, Medal of Honor: Heroes, the next portable release for the Medal of Honor series, was released for the PSP. Heroes was developed by EA Canada, the creators of the Fight Night series.
Medal of Honor: Vanguard was released in 2007 for the PlayStation 2 and Wii. Vanguard was the first instalment to appear on Nintendo's next gen console. Medal of Honor: Airborne was released later that year and was the first instalment to be released on the Xbox 360 and PlayStation 3. Medal of Honor: Heroes 2 was released later that year for the PSP and Wii though both versions were very different.
Opting for a complete franchise reboot EA brought back Medal of Honor but with a new setting: modern day Afghanistan. Danger Close Games, a sub-studio within EA Los Angeles, developed the single player, while DICE worked on multiplayer. The campaign mode was based on events that took place during the US led invasion of Afghanistan in 2001. Players control elite Tier One operators and Army Rangers as they fight the Taliban, referred to in the game as the 'Opposing Force' after some controversy. The online competitive multiplayer features class-based combat with objective focused modes as well as standard deathmatch.
Danger Close once again developed the sequel, Medal of Honor: Warfighter, this time handling both single and multiplayer duties. Warfighter is once again set in Afghanistan as players control elite special forces. The game uses DICE's Frostbite 2.0 engine, which was built from the ground up for Battlefield 3.
