What each player can do here

P1 · Kait (JD in Act I)
  • The chapter is open: the Skiff takes you between the towers, the side missions and the mine.
P2 · Jack or Del
  • A co-op partner can play Jack as a support seat.
  • New module: Cloak, which hides you for a short time.

If your skill levels differ: Uneven pair: the newer player can take Jack, the support robot (scans, fetches, opens doors and revives), while the steadier shot takes a soldier seat and carries the gunfights. How to split the roles

The old COG wall

Part 1 of 4. Open the wall to reach the wider valley.

  1. BothRide to the old COG wall and have Jack open its gate.
  2. BothSnipers hold the room inside; deal with them, climb the ladder, and have Jack open the way on from the console.

The north tower

Part 2 of 4. Get the signal data from the first tower.

  1. BothTwo comm towers need visiting, north and east.
  2. BothOn the way to the north tower, a small shield drone (a Bastion) protects a big gunner; take out the drone, then the gunner.
  3. BothA Warden waits near the tower with smaller enemies; thin those out, then knock its helmet off and go for the head.
  4. BothInside, Jack connects to the computer; move the scanner onto the signal to pull the data.
  5. BothTake the new module from the desk (Cloak) and use it to get past the turrets you set off.

Where people tend to fall

  • On frozen lakes, breaking the ice drops enemies into the freezing water.

The east tower

Part 3 of 4. Climb through the storm and power the second tower.

  1. BothOn the climb, rolling ice boulders and falling shards can kill outright; move from solid cover to solid cover.
  2. BothThe tower has no power: send Jack into the maintenance shaft, then use the console to find the signal.

The abandoned mine

Part 4 of 4. Get explosive fuel from the mine and break through the ice.

  1. BothAt the marked spot on the ice, Jack finds something below; you need explosive fuel from the abandoned mine to get to it.
  2. BothA fight on the ice waits at the mine; watch the enemy with the explosive launcher.
  3. BothJack opens the mine entrance while enemies come from every side; hold them off until he is done.
  4. BothInside, Jack carries the fuel canister; keep enemies off him, because the canister has its own health bar.
  5. BothTake the fuel back to the marked spot and break through; there is no coming back to the valley after this.

Extras and notes
