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.

Tips

  • Turrets will not receive new items that Engineer picks up after they have been deployed. Their items are only updated upon redeployment.
  • Turrets will not inherit Queen's Gland.png Queen's GlandBgBoss.pngQueen's Gland.pngQueen's Gland
    Recruit a Beetle Guard.

    Every 30 seconds, summon a Beetle Guard with bonus 300% damage and 100% health. Can have up to 1 (+1 per stack) Guards at a time.

    Every 30 seconds, summon two Solus Probes that gain +100% (+100% per stack) damage per ally on your team.
    , Focused Convergence.png Focused ConvergenceBgLunar.pngFocused Convergence.pngFocused Convergence
    Increase the speed of Teleporter charging... BUT reduce the size of the zone.

    Teleporters charge 30% (+30% per stack) faster, but the size of the Teleporter zone is 50% (-50% per stack) smaller.
    , Lepton Daisy.png Lepton DaisyBgUncommon.pngLepton Daisy.pngLepton Daisy
    Periodically release a healing nova during the Teleporter event and 'Holdout Zones' such as the Void Fields.

    Release a healing nova during the Teleporter event, healing all nearby allies for 50% of their maximum health. Occurs 1 (+1 per stack) times.
    , Halcyon Seed.png Halcyon SeedBgBoss.pngHalcyon Seed.pngHalcyon Seed
    Summon Aurelionite during the Teleporter event.

    Summon Aurelionite during the teleporter event. It has 100% (+50% per stack) damage and 100% (+100% per stack) health.
    , and Warbanner.png WarbannerBgCommon.pngWarbanner.pngWarbanner
    Drop a Warbanner on level up or starting the Teleporter event. Grants allies attack and movement speed.

    On level up or starting the Teleporter event, drop a banner that strengthens all allies within 16m (+8m per stack). Raise attack and movement speed by 30%.

  • Turrets will inherent equipment items and items that influence other skills slots:
    • Acquiring the Visions of Heresy.png Visions of HeresyBgLunar.pngVisions of Heresy.pngVisions of Heresy
      Replace your Primary Skill with 'Hungering Gaze'.

      Replace your Primary Skill with Hungering Gaze.

      Fire a flurry of tracking shards that detonate after a delay, dealing 120% base damage. Hold up to 12 charges (+12 per stack) that reload after 2 seconds (+2 per stack).

      Survivor: Heretic
      , which increases both their damage and procs substantially while also giving Engineer himself a more usable primary skill.
    • Acquiring Hooks of Heresy.png Hooks of HeresyBgLunar.pngHooks of Heresy.pngHooks of Heresy
      Replace your Secondary Skill with 'Slicing Maelstrom'.

      Replace your Secondary Skill with Slicing Maelstrom.

      Charge up a projectile that deals 875% damage per second to nearby enemies, exploding after 3 seconds to deal 700% damage and root enemies for 3 (+3 per stack) seconds. Recharges after 5 (+5 per stack) seconds.
      and Strides of Heresy.png Strides of HeresyBgLunar.pngStrides of Heresy.pngStrides of Heresy
      Replace your Utility Skill with 'Shadowfade'.

      Replace your Utility Skill with Shadowfade.

      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.
      will be passed onto the turrets, but they are only scripted to use their primary attack so they will have no effect.
    • Likewise, most equipment items will do nothing unless they have a passive effect, even if the turrets also possess Gesture of the Drowned.png Gesture of the DrownedBgLunar.pngGesture of the Drowned.pngGesture of the Drowned
      Dramatically reduce Equipment cooldown... BUT it automatically activates.

      Reduce Equipment cooldown by 50% (+15% per stack). Forces your Equipment to activate whenever it is off cooldown.
      • Engineer's turrets will become Elite if the Engineer has any Elite equipment, as turrets inherit the Engineer's equipment, and the Elite equipment activates passively.
  • The TR12 Gauss Auto-Turrets and TR58 Carbonizer Turrets have almost identical damage output and proc rate, making on-hit items like the Tri-Tip Dagger.png Tri-Tip DaggerBgCommon.pngTri-Tip Dagger.pngTri-Tip Dagger
    Gain +10% chance to bleed enemies on hit.

    10% (+10% per stack) chance to bleed an enemy for 240% base damage.
    universally good for both.
  • The turret's attacks do not have an implicit maximum range, rather the turrets have a maximum range where they will notice and fire upon a target, with the TR58 Carboniser Turrets featuring a much shorter maximum range than the TR12 Gauss Auto-Turrets. This remains true even when their primary attack is replaced by Hungering Gaze.png Hungering GazeHungering Gaze.pngHungering Gaze (Primary)Fire a flurry of tracking shards that detonate after a delay, dealing 120% base damage. Hold up to 12 charges (+12 per stack) that reload after 2 seconds (+2 per stack).

    .
  • Acquiring a Purity.png PurityBgLunar.pngPurity.pngPurity
    Reduce your skill cooldowns by 2 seconds. You are unlucky.

    All skill cooldowns are reduced by 2 (+1 per stack) seconds. All random effects are rolled +1 (+1 per stack) times for an unfavorable outcome.
    will reduce the cooldown of Thermal Harpoons (and Hungering Gaze) to 0.5s. When using both Purity and Visions of Heresy, the turrets' raw damage output is dramatically increased to 4 times their normal amount. However, this sacrifices random chance effects like on-hit items in favor of pure damage.
  • Both Pressure Mines and Spider Mines can be stuck onto the outside surface of the Bubble Shield. Crowbar.png CrowbarsBgCommon.pngCrowbar.pngCrowbar
    Deal bonus damage to enemies above 90% health.

    Deal +75% (+75% per stack) damage to enemies above 90% health.
    are highly useful for both mines.
  • Placing Spider Mines on elevated positions may allow them to jump onto airborne enemies. They can also be placed onto allies and other Survivors, unlike the immobile Pressure Mines.
  • Stacking Bandolier.png BandolierBgUncommon.pngBandolier.pngBandolier
    Chance on kill to drop an ammo pack that resets all skill cooldowns.

    18% (+10% per stack) chance on kill to drop an ammo pack that resets all skill cooldowns.
    can lead to constant uptime of Bubble Shield, allowing for good cover from Wisps and Titans as the game progresses. It also proves useful to refresh the Turrets' cooldown, giving the player backups in case one of them gets destroyed.
    • Be wary that TR58 Carbonizer Turrets can pick up ammo packs by walking past them. This may not be an issue if they have Visions of Heresy.
  • A single Hardlight Afterburner.png Hardlight AfterburnerBgLegendary.pngHardlight Afterburner.pngHardlight Afterburner
    Add 2 extra charges of your Utility skill. Reduce Utility skill cooldown.

    Add +2 (+2 per stack) charges of your Utility skill. Reduces Utility skill cooldown by 33%.
    allows for nearly 100% uptime of Bubble Shield.
  • The Bubble Shield can be used an effective method to avoid the Wandering Vagrant.png Wandering Vagrant'sWandering Vagrant.pngWandering Vagrant - Boss
    Gentle ProtectorHP: 2100 (+630 per level)
    Damage: 6.5 (+1.3 per level)
    Class: Ranged
    Speed: 6 m/s
    Armor: 15
    Genesis Supernova.
  • Moving the targeting reticle of Thermal Harpoons off of a target resets the lock-on delay, allowing the player to immediately target them again. This means that by swiping the reticle back and forth over a single or multiple targets, the player can lock on much faster.
  • Stacking several Bustling Fungus.png Bustling FungusBgCommon.pngBustling Fungus.pngBustling Fungus
    Heal all nearby allies after standing still for 1 second.

    After standing still for 1 second, create a zone that heals for 4.5% (+2.25% per stack) of your health every second to all allies within 3m (+1.5m per stack).
    and placing TR12 Gauss Auto-Turrets beside one another is an effective method for dealing with bosses and high-damage enemies, as it provides a small zone of healing readily defended with the addition of a deployed Bubble Shield. Be wary that melee-oriented monsters may still knock Engineer out of the healing radius or the shielded area.
    • It is not recommended to pick up Transcendence.png TranscendenceBgLunar.pngTranscendence.pngTranscendence
      Convert all your health into shield. Increase maximum health.

      Convert all but 1 health into regenerating shields. Gain 50% (+25% per stack) maximum health.

      Fire haunting skulls when healed.

      Store 100% (+100% per stack) of healing as Soul Energy. After your Soul Energy reaches 10% of your maximum health, fire a skull that deals 250% of your Soul Energy as damage.
      , and as many Bustling Fungus.png Bustling FungusBgCommon.pngBustling Fungus.pngBustling Fungus
      Heal all nearby allies after standing still for 1 second.

      After standing still for 1 second, create a zone that heals for 4.5% (+2.25% per stack) of your health every second to all allies within 3m (+1.5m per stack).

      if using the TR12 Gauss Auto-Turrets, as the Weeping Fungus will not benefit them and they will not be able to heal Engineer.
  • TR12 Gauss Auto-Turrets can block each other's shots if they're placed too close to each other, so some care must be taken to space them out just enough to still benefit from items such as Bustling Fungus.

  • TR12 Gauss Auto-Turrets can be used to press the pressure plates on Abandoned Aqueduct.
    • Though TR58 Carbonizer Turrets can activate them as well, these turrets are liable to walk off the pressure plates.
  • A very risky but rewarding strategy is to acquire the Fuel Array.png Fuel ArrayBgEquipment.pngFuel Array.pngFuel Array
    Looks like it could power something. EXTREMELY unstable...
    at the start of a run. Each turret will get its own Fuel Array and explode when sufficiently damaged, dealing huge damage to whatever was attacking it. This requires the player to dodge well enough to avoid exploding themself, however. This strategy is much more viable in multiplayer, as dying from the Fuel Array will not end the run.

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.
