    Past the grenades, climb down a yellow ladder and go through another door.

    Quicksave immediately after the last door.

    Get out the crossbow, enter zoom mode, and shoot the assassin's head when she turns left.

  19. 19
    Fire an AR grenade above the midpoint of the second set of stairs.

    Alternatively, crouch-walk up the right side of the first set of stairs with C4 satchels.
  21. 21
    Toss a satchel onto the floor just past the stairs, stand up, run back, and detonate when the assassin appears.
  22. 22
    Go up the stairs and along the left walkway to reach the area where you sniped the assassin.

  32. 32
    Go back to the short hallway and fire hornets over the explosive barrels towards the grunt-opened door.
  33. 33
    If a grunt teleports in nearby, turn and use altfire hornets on nearby explosive barrels.
  34. 34
    Sneak-shoot the grunt with the crossbow if the explosion doesn't kill it.
  35. 35
    Fire more hornets toward the grunt-opened doorway, moving to see through it if needed.

  • Utilize cover (press the cover button to crouch behind walls or objects) provided by pillars and storage containers when engaging enemies.
  • Conserve ammo by using environmental hazards like explosive barrels when possible.
  • The Gluon Gun is a powerful weapon, use it to clear out remaining enemies efficiently.
