Jack Companion Guide

Jack, also known as Subject Zero, is a powerful and volatile biotic with a troubled past. Escaping from a Cerberus facility, she joins Shepard with a deep-seated distrust of authority and a penchant for explosive biotic power. Her loyalty mission, "Subject Zero," delves into her traumatic history and is crucial for her emotional stability and combat effectiveness.

Jack is a pure biotic powerhouse, specializing in close-to-mid-range combat. Her abilities are focused on overwhelming enemies with raw biotic force, crowd control, and devastating biotic explosions. Her playstyle is aggressive and high-risk, high-reward, making her a thrilling but demanding companion.

Jack's Abilities and Strengths

  • Class: Jack is an Adept, meaning her focus is entirely on biotic powers.
  • Sature Ability: Jack's signature ability is Pull, which allows her to lift enemies off the ground and group them together, setting them up for devastating biotic combos.
  • Biotic Mastery: She possesses a wide array of powerful biotic abilities, including Shockwave and Warp, which can strip enemy defenses and deal significant damage.
  • Loyalty Mission: "Subject Zero" involves confronting the individuals responsible for her horrific upbringing. Completing this mission allows Jack to confront her past, leading to her loyalty and unlocking her ultimate biotic ability, Locust, a rapid-fire biotic attack.

Recommended Jack Build

When upgrading Jack, prioritize the following:

  1. Pull Upgrades: Focus on upgrades that increase the number of enemies affected by Pull and the duration they are held. The final upgrade, Nemesis Pull, allows her to lift multiple targets simultaneously.
  2. Biotic Damage and Recharge: Invest in upgrades that boost the damage of her biotic powers and reduce their cooldown times. This ensures she can consistently unleash biotic devastation.
  3. Locust: Maximize the effectiveness of Locust by upgrading its damage and rate of fire. This ability is incredibly potent for quickly eliminating priority targets.

Combat Tactics with Jack

Jack excels when positioned to maximize her biotic combos. Use her Pull to group enemies together, then follow up with powers like Shockwave or Warp to trigger biotic explosions. Her aggressive nature means she can be effective in mid-range engagements, but be mindful of her lower defensive capabilities. Against shielded or armored enemies, Warp is invaluable for stripping their defenses, allowing other squadmates to capitalize.

Jack's loyalty mission becomes available after recruiting her and progressing through the main story. Completing it is essential for her personal growth and for unlocking her full combat potential, making her a truly formidable biotic force.
