Zero Hour

A free-to-play, timed exotic mission through the ruined Old Tower in the Pinnacle Ops. You race the clock against the House of Salvation, run a parkour gauntlet, solve SIVA-vault puzzles, and beat Siriks to earn Outbreak Perfected — the SIVA-nanite pulse rifle, now fully craftable through repeat clears.

The Fiction

Why you're here

The clock isn't just a difficulty knob — it's a race against the Fallen for a resurrected plague. Here's the story behind the run.

A plague reforged first

The House of Salvation breaks into the ruined "Old Tower" — destroyed in the Red War — to recover the dormant SIVA-nanite frame of Outbreak Prime. You race the collapsing Tower to reach the SIVA vault before they do.

Getting there first is the reward. You reforge the gun as Outbreak Perfected — the SIVA-nanite pulse whose stacking-nanite perks are the resurrected plague-tech the whole mission is scrambling to secure.

Beat the Fallen to the vault, wake the nanites on your terms instead of theirs, and carry the plague out as a weapon rather than a threat.

The Reward

Outbreak Perfected & how to craft it

Exotic · Kinetic Pulse Rifle · SIVA

Outbreak Perfected

Intrinsic — The Corruption Spreads: sustained fire releases SIVA nanites that deal escalating damage to a target, ramping the longer you stay on it. The nanite swarm is its whole identity — a primary that out-grinds tougher health pools the more you commit to one enemy.

Craft it: your first completion drops a Deepsight Outbreak Perfected. Take it to the Relic in the Enclave on Mars and extract its essence to unlock the craftable pattern, then build your own copy. Each repeat clear awards an intrinsic crafting upgrade, and the three optional in-mission vault puzzles feed the enhanced "The Corruption Spreads" intrinsic via the Vaulted Obstacles Triumph.

Catalyst: Disease Vector comes from the catalyst path and boosts SIVA-nanite damage; precision final blows charge it (the Director’s reward preview shows the tier).

How to start

Open the Director and launch Zero Hour from Pinnacle Ops at the Old Tower ruins. It is permanently available and free-to-play.

Pick a difficulty from Advanced to Ultimate, then go; the Director shows the time limit for your setup, and beating it adds score. The timer starts immediately, so the entire run is one continuous push.

What to bring

  • High mobility (aim for ~80+) and a movement-friendly subclass — the parkour sections are unforgiving.
  • Burst or explosive heavy — rockets, GLs, or a strong Super for the Brig miniboss and the Fallen Walker.
  • Outbreak Perfected itself once you own it, since the vault puzzle is solved by shooting symbol panels with it.
  • Topped-off special and heavy ammo before the final arena.
The Route

Walkthrough

A timed sprint through the Old Tower: combat arenas, collapsing parkour, a sweeper-bot maze, and a symbol puzzle, ending on Siriks. The clock runs the whole time — keep moving.

Launch Zero Hour from the Pinnacle Ops node at your chosen difficulty; the timer starts immediately; the Director shows the time limit for your setup, and beating it adds score.
Tower Plaza: fight through Shanks, Vandals, and a Brig miniboss — use the plaza stairs for cover and pick off snipers before pushing forward. The first optional vault-puzzle panel sits above the debris here.
Tower Hangar: clear a tight arena of Servitors and a Fallen Walker. There's little cover, so a Super or explosive heavy earns its slot.
Covert Passage parkour: cross the collapsing platforms and grates, activate silo switches and ride the rotating exterior platforms, descending toward the vaults.
Work through the descent sections — the TR3-VR sweeper maze and the spinning fan shaft. In the maze, hug the outer wall and flip the four corner switches while dodging the sweeper bot; tuck into the wall recesses when it sweeps past. In the fan shaft, land on the fan hubs and drop through the red pillar lights, avoiding Explosive Shanks.
Vault panel puzzle: shoot the symbol panels with Outbreak Perfected in the sequence shown on the vault monitor to disarm the trapped floor and bank intrinsic progress. The symbols and code rotate weekly.
Final arena: defeat Siriks of the House of Salvation before the timer runs out. Clear his adds and turrets between damage windows, and don't run dry on ammo.
Claim Outbreak Perfected from the reward chest. On a first clear you also speak with Ada-1 to lock in the weapon and its pattern, and take the Deepsight copy to the Relic in the Enclave on Mars to unlock crafting.
The Details

Mechanics & the boss

Key mechanics

Strict timer. The full run must be done in one push — every puzzle and jump burns the clock, and the Director shows the time limit for your setup, and beating it adds score.
Parkour platforming. Collapsing platforms, rotating exterior silos, and a spinning fan shaft where you drop through red pillar lights.
TR3-VR sweeper maze. Flip the four corner switches while a sweeper bot patrols; duck into wall recesses when it nears.
Symbol-shooting vault puzzle. Shoot the panels with Outbreak Perfected in the monitor's order; the sequence rotates weekly.
SIVA-nanite weapon perks. The mission's reward and its catalyst both lean on stacking nanite damage on a single target.

Boss · Siriks, of the House of Salvation

The final arena is a straight fight against Siriks — the Fallen leader serving Eramis. There's no immunity-puzzle gate like Whisper's Ogre; the challenge is surviving the add pressure and turrets while keeping the clock alive.

Clear adds and any turrets or Champions before each damage window, then commit your heavy. Running out of special and heavy ammo against his adds is the most common wipe — top off before you walk in.

Lore lens · why it works

SIVA is self-replicating Golden Age nanotech, so the vault’s Rasputin-era symbol lock guards it and the weapon’s stacking-nanite damage is literally SIVA swarming a target. The TR3-VR sweeper is a lingering security drone still patrolling the ruin — time the corridors around its rounds. Siriks is a straight fight because the real mechanic is the timer: the whole mission is a race to the SIVA before the House of Salvation claims it.

Difficulty & rewards. Pinnacle Ops lists Advanced, Expert, Master, Grandmaster and Ultimate; the Director shows the time limit for your setup, and beating it adds score. Every tier drops Outbreak Perfected plus the first-clear Deepsight for the craftable pattern and intrinsic crafting upgrades; higher tiers add harder parkour and Champions and raise the reward tier, and the Catalyst follows the Director’s reward preview. The exotic ship cosmetic (the Vimana Junker) is tied to the Vaulted Obstacles Triumph rather than to the difficulty itself.
Don't Wipe

Tips & common mistakes

Watch the clock. The timer never pauses for puzzles or jumps, so don't over-explore on a learning run — use a lower-difficulty run to drill the route before you chase the catalyst.
Bring high mobility (~80+) and a movement subclass for the parkour, plus a burst or explosive heavy for the Brig and the Walker.
Top off special and heavy ammo before the final arena — running dry against Siriks's adds is the most common wipe.
Kill the boss-arena turrets and Champions immediately and clear adds before each damage window. Check the vault monitor each reset — the symbols and code rotate weekly, so last week's solution won't carry over.
Build Pairing

Best artifact for this exotic

Outbreak Perfected is a kinetic primary whose damage builds the longer you keep nanites on a target, so pair it with the artifact that keeps a kinetic primary fed and firing. The Artifact 2.0 layer accelerates the build — it doesn't gate it.

Primary pick

Encrypted Data Disk

Why: its kinetic-weapon economy — Kinetic Synthesis ammo bricks and the Kinetic Siphon helmet mods — keeps Outbreak Perfected's magazine and reserves topped so the sustained SIVA-nanite ramp never has to stop for ammo. A primary that wants to stay on one target for a long time is exactly the loadout this artifact rewards.

Alternative: NPA Repulsion Regulator — on an Arc or Void build, its weapon-mod discounts and ability economy support a primary-anchored loadout, freeing energy and ability uptime around Outbreak as your damage engine.

Reminder: artifact perks are disabled in Competitive and Trials but active in all PvE — so for a Pinnacle Ops run, slot freely. See the PvE Weapons page for the full loadout around Outbreak Perfected.
