Master stealth and combat in The Callisto Protocol's tunnel sections. Learn enemy patterns, perfect dodges, and essential controls to survive the horrors of Black Iron Prison.

Walkthrough
  1. 1
    Begin by starting a new game on Maximum Security. Pause the game and enter Photo Mode to unlock the 'Mugshot' achievement.
  2. 2
    Proceed down the initial hallway and enter the first door on the left. Open the locker inside to find your first collectible, a Bios (1/43).
  3. 3
    Continue into the cargo bay. Learn to vault over boxes using !cn_LSu!cn_A and mantle using the same buttons.
  4. 4
    As you approach a flaming hole, you will unlock the 'The Outer Way' achievement for finding the Outer Way boarding craft.
  5. 5
    Crouch using !cn_B, shimmy through a tight space with !cn_LSu, and sprint using !cn_LB. After a cut-scene, hold forward on the left stick to return to the captain's chair, ending Chapter 1.
  6. 6
    In Chapter 2, after a dream sequence, explore your cell. Exit and turn right to find a staircase. Descend to meet Elias, who will give you a shiv, unlocking the 'Desperate Times' achievement.
  7. 7
    Use the shiv on the control panel to open Elias's cell and shimmy through the doorway.
  8. 8
    In the next room, learn combat mechanics: hold !cn_LSl or !cn_LSr to dodge before an attack. Alternate dodges for consecutive attacks. Attack with !cn_RT after an enemy finishes their combo.
  9. 9
    Defeat the two inmates and the first Biophage. Aim to dismember enemies to unlock the 'Flesh Wound' achievement.
  10. 10
    Unlock Elias's cell with the computer console. Follow Elias to the elevator and take it down a level.
  11. 11
    Exit the lift, turn left, and crouch under debris. After defeating another Biophage, practice perfect dodges by flicking !cn_LS left or right just as an opponent winds up for an attack. This will unlock the 'Float Like A Butterfly' achievement after five successful dodges.
  12. 12
    After the fight, find a glowing green wall storage unit to receive a health injector and learn how to use it.
Tips
  • The game is significantly easier after recent patches, making Maximum Security manageable.
  • Pay close attention to enemy body language to anticipate attack patterns and dodge effectively.
  • Perfect dodge timing is crucial and requires performing the action earlier than you might expect.
  • The 'Float Like A Butterfly' achievement can be buggy; it's best to attempt it early in the game.
  • Remember to mash !cn_Y to escape grabs and stomp on defeated enemies with !cn_Y.
