Act 4

1. Hope and Ruin

13 collectibles · 14 Hard Cases · 3 secondary objectives · map available

A large open area through the wreck of central Kalona, and the slowest chapter of the act to clean up. You start in a fort with a memorial and work outwards: across the bridge, through a cathedral and its cemetery, past the Regalia Hotel and a crater, and through Cooper Commons and Kalona Square to the opera house.

• 1

  The fort and the cathedral

  Read the memorial wall before you leave the fort through the hole in the wall, then cross the bridge. The cathedral ruins and the cemetery behind them come next; this is where you split from Zee and Michaelson. Out of the cemetery, the road on the left usually has a Bile Frog and Wretches on it.

• 2

  The Regalia Hotel and the crater

  Four Hard Cases sit in and around the hotel, so sweep it before leaving by the back staircase. The big crater beyond is where Locust attack; one of the buildings around it has several snipers, so clear them before you go hunting for the apartment collectible near them.

• 3

  Cooper Commons and Kalona Square

  The main route takes you through Cooper Commons, at the bottom of the map, where Missing Convoy means killing Spore Matrons. Clear the Locust in Kalona Square before you search it; R.I.G. Experiment is in the building on its west side.

• 4

  The opera house

  Leave the square through the gate at the top of the map and climb to the plaza in front of the opera house, where Locust and Reavers are waiting. The opera house itself, the street down its left side and the clocktower down its right side hold the last items and Clocktower Defense, a wave defence.

2. Technical Difficulties

2 collectibles · 3 Hard Cases · no secondary objectives

A short, mostly scripted chapter underground and on the trains. The one thing to plan for is the first train stop.

• 1

  The first train stop

  Clear the Locust on the tracks at the station and board the next train. When it pulls into a station lit red and full of Locust, step off, take the tags from the body just outside the doors and get back on before it leaves. There may not be time to kill everything first: grab the tags, get back aboard and fight from there.

• 2

  The blockage and the skytrain

  The train stops at a blockage and you continue on foot. Before taking the platform exit, check the far side for the poster. Out of the subway there is a fight, then the climb to the yellow skytrain platform.

In route order

1. Hard Case In the wider room with a bench near the start, across from the supply cache.
2. Collectible COG Tags of Sergeant Aman Landry When the train first stops at the red-lit station full of Locust, step off and take the tags from the body just outside, then get back on before the train leaves. Miss it and you replay the chapter.
3. Collectible No 80 Graffitied Poster When the train stops at the blockage and you get off, cross the platform and go left instead of taking the exit; on the wall.
4. Hard Case Through the platform exit, along the corridor; in the small room straight ahead before you turn left.
5. Hard Case Up the steps to the yellow skytrain platform, look right: across a gap at the platform's edge, before you board.

3. Tough As Nails

14 collectibles · 12 Hard Cases · 4 secondary objectives · map available

The longest chapter of the act and one of the last open areas in the game: Prospect Bay's train yard, docks, factories and power station. It starts after you talk to Auntie in the pub.

• 1

  The open area

  The power station area is bigger than it looks, with side passages. Scout before you engage, and use the space so you are not flanked from the sides.

• 2

  Weapons warehouse and power station

  The main objectives send you to load a truck at the weapons warehouse and to the power station to bring the power back. Death from Above, on the roof of the Armadillo factory, only opens once the power is restored, so come back for it.

• 3

  The secondary objectives

  Special Cargo ends with a container to open, and the Imulsion Blast Charge collectible is inside it. In Trapped Locust you bring a train car in from a console and then open it, so set up your position before you release what is inside. Fire in the Hole means killing the Locust that come up below the building above the helipad.

• 4

  The control tower

  The chapter's last main objective is a climb up the control tower. The Docking Registry is on a console at the top, and it is the last collectible here.

4. Signals

5 collectibles · 5 Hard Cases · no secondary objectives

A short chapter whose goal is to get long-range communications working; the comms equipment only works with the power station back online.

• 1

  The gas station and the substation

  Clear the Locust at the gas station; two Hard Cases and the mints are there. Next is a power substation with Locust guarding it, then the woods.

• 2

  The comms tower

  Through the woods, past a fallen tree and a bridge, you reach the comms tower. After its cutscene, check the area outside (the shooting range and the lookout tower) before you go into the station, where the last two collectibles are.

In route order

1. Hard Case At the gas station, round the back of the white van on the right of the car park; in the side opening.
2. Collectible Infinity Mints In the gas station kiosk, round the left of the counter, on the floor in the corner.

5. Paths Diverge

2 collectibles · 4 Hard Cases · no secondary objectives

From a street through a warehouse and a train yard to the docks and a big fight.

• 1

  Warehouse and train yard

  Turn round as soon as the chapter starts: the first tags are right behind you. At the end of the street go through the warehouse. In the train yard the route takes you through the building on the right to get round a barricade, but the top left corner is worth a detour first.

• 2

  The docks and the Brumak

  Clear the Locust at the docks so Auntie can use the PA system. The chapter's big fight is against a Brumak with Spore Matrons; the arena's Hard Case, by a police car on the left before the gate, can be picked up during the fight or after it.

In route order

1. Collectible COG Tags of Lance Corporal Aniyah Musa At the very start of the chapter, in the corner behind you to the left; on the ground.
2. Hard Case In the warehouse at the end of the starting street, in the back right room.

5. Hard Case In the room at the upper back left of the train-yard buildings, on the left as you enter, by a supply cache.
6. Hard Case In the Brumak arena: by a police car on the left before the gate, during or after the fight.

6. Critical Failure

5 collectibles · 8 Hard Cases · no secondary objectives

Inside the Timgad refinery, ending in a boss fight. Most of what there is to find is in the rooms just before that fight, and the boss cuts them off.

• 1

  Into the refinery

  The first building has a Hard Case and a collectible together on the main desk. Take the long elevator up, then crawl through the pipe at the Cooling System Access, climb the ladder and fight your way to the main building.

• 2

  Split into pairs

  The squad splits into pairs and Marcus goes with Lucas, who use a keycard to open the way on. Once you regroup, a double door leads out to a Boomer and other Locust. The route then goes through the Amber Labs office and down a corridor.

• 3

  Before the boss

  The room with the large green schematics holds the research journal and a Hard Case; the next room, round the Imulsion in the floor, has another Hard Case opposite a supply cache. Take all three before you move on: once the boss fight starts, the journal can no longer be picked up.
