Why We Fight is the first chapter in Homefront's singleplayer mode.
Welcome to 2027. It's been two years since the KPA attacked the United States. You are a former Marine pilot just trying to keep a low profile. A week ago, you received a draft notice; the Koreans want to recruit you. But they're not the only ones.
The level begins with the player (Robert Jacobs) waking up and getting out of bed. There is someone at the door and the player's first objective is to open it. Upon doing so, Jacobs is pinned against the wall by a KPA policeman while his comrade has his gun trained on Jacobs. Colonel Jeong steps into the room and has the player arrested for not signing up for the Korean military. Jacobs is hit by the man with his gun trained on him by the buttstock of his gun and thrown into the hall and down the stairs, knocking the player momentarily unconscious.
When Jacobs come to, the player is dragged into a bus heading to a re-education camp. Inside, a policeman shoves Jacobs into the back of the bus. Another shoves the player into a seat and straps the player down. The bus starts and another "criminal," also a former pilot, talks to the player as the bus rolls down the street. The player can see mass arrests and several executions committed by the KPA police force if the player looks out the window, including holding a bag over an American's head and also shooting a child's parents in front of him, according to the story, this was done as a response to the resistance's advances in the region, and the former pilot will talk about the cruelty of the Koreans and when they get to where they're going, the player and he will have to stick together. While the bus is driving through an intersection, a truck crashes into the bus flipping it.
As Jacobs look around, Connor of the American Resistance enters the bus, and stabs the Korean policeman. He tells Jacobs to pick up the M9 from the dead Korean and you both exit the bus. Rianna is outside the bus and the three run to the nearest building. In an alley a pair of KPA policemen jumps the player and the player eliminates them both. Connor states that there's "no going back now, you have Korean blood on your hands." Jacobs, Connor, and Rianna make their way though the neighborhood, including an abandoned gas station and a crashed airplane. The group meets up with Boone Karlson. Upon arriving at a group of houses Rianna and Conner argue briefly about whether they should have come before Boone tells them that that's enough and talks to Jacobs. KPA start attacking and the Resistance members move into a house. An unnamed Resistance member is shot. Hopper tries to keep him alive.
Hopper gives the player Goliath's rocket launcher targeting system to clear out the remaining Koreans with Goliath before the level ends in an explosion.
