The Engineer is a playable character in Risk of Rain 2.

With an assortment of deployable gadgets, the Engineer's strength comes not from him alone, but rather his ability to set up a variety of defensive measures.

The Engineer's signature ability is his deployable turrets, which gain the same items that Engineer himself has. This makes him unique, as item selection doesn't necessarily come down to what benefits himself, but also what can benefit his turrets.

Completing the Engineering Perfection challenge will unlock Engineer as a playable survivor.

Behaviors

For an explanation of how these behaviors are implemented read about Enemy AI. This section only applies when the character is controlled by AI.

Engineer

  1. Use primary (paint Harpoons) and strafe: Engineer must be within 60m from the target. This behavior is active for 1.5 seconds and cannot be selected twice in a row. While it uses the primary skill button, it is in the targetting context of Thermal Harpoons.
  2. Use secondary (cancel Harpoons) and strafe: this behavior is active for 0.1 seconds and is used in the targetting context of Thermal Harpoons when there is no line of sight to the target or to cancel the painting mode early if all Harpoons have been queued.
  3. Use secondary and strafe: Engineer must be within 17m from the target. The character will sprint and the behavior cannot be selected twice in a row.
  4. Use special: Engineer must be within 22m from the target and this behavior cannot be selected twice in a row.
  5. Use utility (Thermal Harpoons): Engineer must be within 20-60m from the target, have line of sight, and be aiming at it. This behavior is active for 0.1 seconds and cannot be selected twice in a row.
  6. Use utility (Bubble Shield): Engineer must be within 12m from the closest ally. Since there is no implicit use of the Special skill with Shadowfade ShadowfadeShadowfadeShadowfade (Utility)Fade away, becoming intangible and gaining +30% movement speed. Heal for 18.2% (+18.2% per stack) of your maximum health. Lasts 3 (+3 per stack) seconds.
    Survivor: Heretic
    , it will never be used.
  7. Use primary and strafe: Engineer must be within 17m from the target. This behavior cannot be selected twice in a row.
  8. Use primary and run towards ally: Engineer must be within 8-40m from the closest ally. This behavior cannot be selected twice in a row. The intention of this behavior is to stay close to his turrets, but any ally satisfies the requirement. As such, if the player is near the character while also another monster is nearby, in the absence of other skills being off cooldown the character will toggle between using his primary while strafing the player and staying close to the ally.
  9. Use primary and chase: Engineer must be within 20m from the target.
  10. Chase: no requirements.

TR12 Gauss Auto-Turret

  1. Use primary: the Turret must be within 60m from the target, have line of sight, and be aiming at it. The behavior is active for 1 second and a new target will be selected after this.
  2. Search for target: no requirements.

TR58 Carbonizer Turret

  1. Return to leader: the Turrent must be more than 110m from its summoner. This behavior is active for 5 seconds and the Turret will sprint for its duration. A new target will be selected after this.
  2. Use primary and strafe: the Turret must be within 15m from the target and be aiming at it. This behavior is active for 3 seconds and a new target will be selected after this.
  3. Use primary and chase: the Turret must be within 15-25m from the target and be aiming at it. This behavior is active for 1 second and a new target will be selected after this.
  4. Return to leader (version 2): the Turret must be more than 6m from its summoner. A new target will be selected after this. Due to the ordering of the previous behavior, this can only be selected if the Turret is within 110m from its leader and more than 25m from any enemy. The Turret will also not sprint during this and the behavior is intended as a soft leash to the leader when all nearby enemies have been killed.
  5. Do nothing: the Turret's summoner must still be alive and a new target will be selected after this. This is mostly used when the Turret is near its summoner and there are no enemies to engage. Unlike most other allies and drones which have a fallback behavior to chase down enemies when their summoner is dead, this Turret exhibits no such behavior. As such, it will wander aimlessly and attack enemies if it ever gets within range.

Tips

Lore

“The future is now! Cybernetic enhancements – buy them cheap and become the person you’ve always dreamed of being!” 

Cybernetic enhancements were all the rage these days, especially since they were made available for public use. Initially, only military and commercial projects could license the procedures necessary to install cybernetic implants. But those days were long gone, and the concept of “the new human” was taking the galaxy by storm. 

Of course, with any movement, there was backlash.  What of the sanctity of the human body? What about taking pride in your biology? Such arguments were normally laughed off. “Get with the times,” people would say. But one man among many stood out, gaining public attention and starting a counter movement of anti-cybernetics.

The man postulated that mankind was walking on a tight rope – when do the cybernetics end, and where does the human begin? Will mankind end up as a machine species, or will we use our new tech to only better ourselves - without losing sight of what makes us human? The words of this man echoed across the galaxy, leaving a trail of revolution in its wake.
