Iron Front: Modern Warfare

It starts in Hearts of Iron IV. Choose any nation on its own 1936 country screen and start the game. Iron Front takes that nation straight into its first Modern Warfare 2 battle, and the war goes on from there.

• Any nation on the map. 11 have their own historical campaign (Germany, Poland, France, the United Kingdom, the Soviet Union, the United States, Italy, Japan, China, Finland, Ethiopia); every other nation goes to war with its strongest neighbours.
• Your nation, from your own game: its real flag, leader, generals and states, read from your Hearts of Iron IV, with its music playing on the campaign map.
• A medium-length campaign of up to 16 battles across one to three wars: pick which enemy state to attack, or defend when the enemy attacks.
• Generals matter. Before each battle, choose one of your nation's Hearts of Iron IV generals; their real traits become MW2 killstreaks, perks or extra squadmates.
• Every battle is Modern Warfare 2 on a map that fits the state's terrain: you and computer squadmates against computer enemies, with a random loadout. Pick the battle plan: Frontal Assault (Team Deathmatch), Seize the Colours (Capture the Flag) or Hold the Line (King of the Hill). Win, and the state is yours on the map.
• Random events with choices (volunteers, spies, air support, strikes, partisans, enemy offensives), each with a Hearts of Iron IV event picture.
• World news: other nations go to war, annex each other and join your war as the months pass.
• Take enough states or the enemy capital and the enemy capitulates; lose your capital or your war support and it's over. Your campaign is saved between battles.

Solo. Press M on the campaign screen to turn the music on or off.

Needs Hearts of Iron IV and Call of Duty: Modern Warfare 2 (2009). Nothing from either game is included. Hearts of Iron IV runs with a small Iron Front mod, switched on while you play; your mod list is put back afterwards. The battles run in IW4L, the open-source MW2 engine, which loads maps, guns and sounds from your own MW2. Closing Iron Front also closes the Hearts of Iron IV it opened.
