- Help Dunn at the Convenience Store
Follow Dunn through the Goh Mart while he shops. The dialogue choices are flavor only and don't change anything.
- Help Dunn at the Convenience Store
Pay at the counter once Dunn is done, then head outside and walk with the squad until the power cuts out.
- Go to the Stadium
After the blast, stick with the squad through the wrecked street, crouching under the debris in your way.
Checkpoints come often from here on, so don't worry about dying in the rubble section.
- Go to the Stadium
Run to the baseball stadium and get inside through the shutter door, then follow the service corridors to the field.
- Go to the Stadium
On the field, hide behind the supply crates and shoot the paratroopers as they come down.
Aim at the paratroopers closest to the ground first; that's where Skeet Shooting kills are easiest.
- Find the Convoy's Origin
Fall back to the restaurant, refill ammo and armor at the counter, and clear the soldiers in the dining room.
- Find the Convoy's Origin
Move to the parking garage. Go prone behind the parked cars while the enemy convoy rolls past.
- Find the Convoy's Origin
Once the second convoy leaves, head down to the basement level where soldiers are guarding a tunnel.
- Destroy the Tunnel
Kill the tunnel guards, then hold cover against the troops pouring out while the squad pushes the fuel truck toward the opening.
- Destroy the Tunnel
When the truck crashes, grab the RPG from the crates on the left and fire it into the tanker to bring the tunnel down.
Achievements
Kill 10 paratroopers before they land during the baseball field fight.
Rewards for finishing
- Cho Operator
Veteran tips
- The restaurant and tunnel fights get much harder on Veteran. Use the restaurant counter to top up armor and ammo before you move to the garage.
Story recapSpoilers
Story
Park’s joint US-ROK squad is in Hajin City on an ordinary day when the power goes out and artillery starts falling. Their friend Ju Kwon is killed in the first blast, and the squad runs for cover in the city’s baseball stadium, only for North Korean paratroopers to drop onto the field.
After holding the stadium and a nearby restaurant, the squad tracks an enemy convoy back to a parking garage and finds a tunnel that North Korean troops are using to move into the city. They push a fuel truck into the tunnel and Park detonates it with an RPG, collapsing the passage.
A news broadcast closes the mission: North Korea has launched a full invasion of the South, Russian troops are on the move, and there is a manhunt underway for Captain John Price.
