Walkthrough
11 steps across 5 objectives
- Reach the Café
Advance with the team down the road under the elevated rail line, clearing enemies behind the cars and barricades.
Enemies wear red night-vision goggles, which helps tell them apart from friendlies in the dark.
- Reach the Café
Clear the intersection around the café on the northwest corner, then take the outside stairs to the second floor.
Civilians are hiding in a car nearby; don't throw grenades near it. Hitting civilians or friendlies fails the objective.
- Defend the Café
Restock and swap guns at the table inside, then hold the windows with Tiger 0-1.
The MAR-9 on the window sill is good for the long sightlines; the table also has a Han 86 with an underbarrel grenade launcher.
- Defend the Café
Fight off the waves from the right, left and center, then the RPG gunners on the train cars above the street. Only shoot armed enemies; civilians are running past.
- Defend the Café
When a BMP starts shelling the building, get out through the back alley.
- Reach the Bridge
Fall back with the team through the burning blocks behind the café, killing the rooftop shooters, and follow the red flares to the bridge.
Friendlies hold the bridge, so watch your fire as you arrive.
- Mount the Mortar Launcher
After a sniper kills the mortar gunner on the truck, take out the sniper and climb into the truck bed to man the mortar.
- Mount the Mortar Launcher
Shell the enemy groups as Kal calls them out: left, then right, then the rooftops. Use the range gauge on the left to adjust your aim.
Mortar rounds are unlimited, so walk your shots onto the target. Aim for clusters, not single soldiers.
- Mount the Mortar Launcher
Focus your fire on the BMP that rolls up in front of the bridge until it's destroyed.
- Reach the Tunnel
When a helicopter wrecks the truck and the bridge starts to give way, jump down and follow Kal across the collapsing road.
Sliding cars can kill you instantly. The jump through the hanging bus is the likeliest place to die, but it has a checkpoint.
- Reach the Tunnel
Run through the bus and jump out of its windshield, then regroup with the squad at the tunnel to end the mission.
Achievements
Kill 15 enemies with three mortar rounds in a row. Game8's route: range 3, first round on the group in front of the burning hillside building to the left, then two rounds on groups of five or more around the middle of the five parked cars on the road to the right. The game saves after each good shot, so reload if one misses.

Story recapSpoilers
Story
Back in Hajin City, Park is pulled out of the rubble after the tunnel collapse. It’s night, the invasion is in full swing, and the squad, now with Captain Kal, links up with friendly forces holding a café at a key intersection.
The café falls when North Korean armor arrives, and the squad retreats to a bridge, where Park works a truck-mounted mortar to slow the advance. An attack helicopter destroys the truck and breaks the bridge, and the squad barely makes it across to a tunnel.
The bridge collapsing behind them cuts off the retreat. The squad gets out of the city on an evacuation truck, Park struggling with the losses and West insisting the fight isn’t over. Afterward, at Camp Humphreys, Col. Shaw briefs the troops on a counteroffensive and Kal offers the squad a front-line assignment.
