Boarding Action mission walkthrough

  1. 01

    Board the Triumph of Tolerance

    The mission opens on the Triumph of Tolerance with a Battle Rifle, Magnum and a small boarding party. Clear the first chamber before Johnson finishes opening the route, and treat every mounted turret as the first target in a room. The early climb ends with a pair of Hunters; separate them around the ramps and shoot the exposed backs instead of trying to trade damage.

  2. 02

    Follow the change of plans

    After the first objective falls apart, take the tractor beam down and continue through the training areas. A Needle Rifle is worth keeping because three quick hits can finish shielded targets, and the portable Overshield can be saved for the next hard room. In the Elite training chamber, stop enemies from taking the Ghost and use the different floors to break up the waves.

  3. 03

    Cross the gene forge

    The gene forge introduces Brutes and the Prophet of Harmony’s experiment. Shooting the red device on a Brute can send it into a rage against anything nearby, which is useful as long as you are not standing beside it. Survive the forge waves, push to the upper decks and clear the last room before taking the beam onward.

Completion tips

Turrets, Hunter pairs and late gene-forge waves punish anyone who walks into the middle of a room. Work from doors and ramps, and keep the Needle Rifle once it appears.

  • Plasma Pistol swap-fire is slower here, and staggering a Jackal by shooting its hand is unreliable. Use a charged shot or close for a melee hit.
  • Johnson returns after being downed and draws plenty of fire. Let him pull Hunters or Elites away before you expose yourself.
  • Portable Overshield and Active Camouflage share the same equipment slot, so use the current item before trying to carry another.
