Fatshark’s acclaimed co-op shooter Warhammer 40,000: Darktide is charging back into the fray with its latest free update, Bound by Duty, launching right now on PC and consoles. This patch breathes new life into the game’s roguelike wave-based mode, Mortis Trials, delivering high-stakes chaos for veteran players and newcomers alike.At the heart of Bound by Duty is a revamped Mortis Trials experience. The mode, already a fan-favorite for its punishing, replayable waves of heretical foes, now introduces a brand-new arena that tests your squad’s mettle in unpredictable environments. Picture this: shadowy, industrial hives of Tertium twisted with fresh hazards and layouts designed to force adaptive tactics amid the grimdark horror.
But the update doesn’t stop at scenery. Arm your Ogryn, Veteran, Zealot, or Psyker with innovative new weaponry, ranging from brutal melee upgrades to las-fire innovations that fit seamlessly into the 41st millennium’s arsenal. These tools aren’t just cosmetic—they’re tuned for the escalating threats you’ll face.Enter the new enemy type, a grotesque abomination straight from the warp’s nightmares. This hulking terror brings novel mechanics to the battlefield, demanding coordinated fireteams to exploit weaknesses and survive the onslaught. Expect it to shake up strategies in both solo runs and four-player co-op sessions.”Bound by Duty elevates Mortis Trials to new heights of replayability and intensity,” says Fatshark in the official patch notes. “Whether you’re grinding for Penances or just purging heretics for the thrill, this update ensures every run feels fresh and unforgiving.
“The free update is live today across all platforms—no DLC required. If you’ve been sidelined since Darktide’s last major content drop, now’s the perfect time to dive back in. Pair it with the base game’s free-to-play trial on Steam for a low-risk entry into the hive city’s underbelly.
Everything New
What’s included in the Bound By Duty free update:
● New Mortis Trials arena, Theatre of Rectitude: Re-enter the visions summoned by the ship’s Psyker, Sefoni, in an all-new arena inspired by the Clandestium Gloriana mission and its frozen Adeptus Mechanicus Foundryplex.
● Two new Indulgences archetypes: offering additional buffs expanding the breadth of combat styles within Mortis Trials.
■ Emperor Favored: Grants increase to critical chance and critical damage, plus effects that trigger on critical hits. These buffs stack: early gains may seem modest, but they compound to support powerful crit-focused builds later in a run.
■ Goliath: Centers on mobility and resilience rather than damage reduction: immunity to Suppression and Stagger, stamina boosts, and crowd-control options. One notable buff staggers enemies when you sprint, letting you plow through hordes even when cornered.
● New Memory Echoes: Several new chapters that expand NPC backstories and reveal more of the Mourningstar’s past through Sefoni’s visions between waves.
● New Enemy, Scab Plasma Gunner: A dangerous new Specialist enemy joins Darktide’s roster. The Scab Plasma Gunner wields a powerful plasma weapon, forcing players to adapt their tactics and brace for intense, high-damage attacks. Expect to feel the heat in any mission where this adversary appears.
● New Veteran weapon, the Power Falchion: A single-edged, one‑handed power weapon that plays as a counterpart to the Power Sword. Its Special action works like the Zealot’s Relic Blade: activating the Special action empowers the Falchion until its heat bar fills, at which point it overheats and the Special is locked until the bar empties. This weapon family comes with two marks.
● New Bolt Pistol and Boltgun marks: Bolt Pistol Mk VI Godwyn‑Branx and Boltgun Mk III Locke. Both marks emphasize explosive effects: larger explosions and significantly more explosive damage on hit or kill compared with other marks in their families.
● Talent Reworks and Class balances: increased flexibility and player agency around the Veteran, Zealot and Psyker trees by providing a more open layout. The overarching goal was to bring better balance, more build diversity, and more meaningful choices across all classes. The Ogryn and Arbites talents also got a light touch-up!
● Special Event, Smuggled Munitions: Forces of the Traitorous 6th have raided local plasma weapon caches. Players will have to out these dangerous squads and dispatch them. A flashlight will not go amiss as this event will always be attached to low visibility conditions such as Ventilation Purge, Lights Out or Power Supply Interruption.
● New Havoc Modifier, Contaminated Stimms: Darktide’s endgame mode will have a new modifier joining the existing roster. Face challenging tides of enemies using stimms to reinforce themselves. In addition, the previously run Special event Rotten Armor will return once again as a modifier for Havoc.
● Quality of Life changes: a few improvements will be coming to Darktide, including a dodge counter, a new on-screen indicator showing remaining dodges. This is to ensure players always know when they can evade and when they’re out of effective dodges. Players will also be able to replay missions from the Battle for Tertium campaign.
