Hunter, you have proven your dedication to the cause. It is time to enlighten you, to show you what we have built together. It is time to enter the Sanctuary.

In the simulated universe of the Sanctuary, my data-immortals have fought each other countless times. Through this violence, I have studied and documented their true character. But my study cannot be complete without the power of the Tenno, the most powerful specimen in the system — you. Your duty in this experiment is to kill as many specimens as efficiently as possible. In this chaos, the true nature of these creatures will be revealed... as will yours.

Challenge my specimens within the construct and enlighten me. I will reward you in kind.

—In-Game Description

Sanctuary Onslaught is an endless game mode introduced in Update 22.18 (2018-04-20). The objective is similar to Survival missions, where players must last as long as possible by continuously killing hordes of increasingly difficult enemies, as quickly as possible.

Players are limited to one large room from a random tileset in every zone. In order to advance through the zones, players must maintain efficiency by constantly killing enemies, then entering a conduit at the end of the zone's time limit in order to progress to the next. The opposing faction of enemies encountered in each zone is also randomized on a per-zone basis.

Players must complete The New Strange to access this game mode. To begin, players must talk to Cephalon Simaris at his Sanctuary in any Relay or select "Sanctuary Onslaught" in the Syndicate World State Window tab.

Mechanics[]

Upon starting the mission, players will have to enter a conduit and maintain efficiency meter against increasingly difficult enemies. Each enemy killed in the process will contribute to the overall efficiency, with Eximus enemies contributing more.

Every zone lasts for 2 minutes and 30 seconds. When a zone is complete, Simaris will open a Data-Conduit to a new and harder zone within his Sanctuary. The conduit closes after 30 seconds. Players who have not entered the conduit before then will be extracted with their rewards.

Terminology[]

Rules[]

Simaris has his own rules within his sanctuary, as he seeks to produce an accurate experiment. These are the following rules:

Elite Sanctuary Onslaught[]

Rank yourself among Hunters by facing the most elite specimens of Sanctuary.

—In-Game Description

Elite Sanctuary Onslaught is a higher difficulty mode of Sanctuary Onslaught. In addition to featuring stronger specimens, tilesets and enemies are predetermined every week, and usage of Warframe abilities must be staggered or they will become temporarily disabled.

Rewards[]

Rewards are given per two successful zones in an AABC rotation in both Sanctuary Onslaught and Elite Sanctuary Onslaught to players before they jump into the Data-Conduit.

Hotfix 22.18.8 (2018-04-28)
Sanctuary Onslaught Changes:
We still see Onslaught as a more bite-sized gameplay experience, but combined with the efficiency changes below, how far your team can last should be dictated slightly more by your ability to kill instead of hard numeric limits. The Simulation is alive and ever changing.

  • Removed the increased Efficiency drain when you hit Zone 20 in Sanctuary Onslaught and from Elite Sanctuary Onslaught when you hit Zone 14. Efficiency drain will hit its max rate in Zone 16 of Sanctuary Onslaught and Zone 15 of Elite Sanctuary Onslaught.
  • Added more tiers of increasingly higher level enemies in both Sanctuary Onslaught and Elite Sanctuary Onslaught:
    • Sanctuary Onslaught
      • Level 80-100 in Zone 15
      • Level 110-130 in Zone 20
      • Level 130-150 in Zone 25
    • Elite Sanctuary Onslaught
      • Level 200-220 in Zone 20
      • Level 250-280 in Zone 25
  • Removed unnecessary ice environment textures in the Grineer Shipyard Onslaught tile.
  • Removed an Orokin Derelict tile from Onslaught that was too small - this means that Zone 12 of Elite will have a new tile.
  • Removed an Infested Corpus Onslaught tile that was deemed unsuitable for the Simulation.

Sanctuary Onslaught Fixes:

  • Fixed Clients being perpetually stuck on the loading screen after a Host migration in Onslaught.
  • Fixed cases of Conduits not materializing after a Host migration occurs.
  • Fixed cases of Clients being trapped in the old Zone after the Host transitions through the Conduit first and disconnects on the other side.
  • Fixed Efficiency continuing to drain after a Conduit has appeared and you have yet to pass through it. Once all players are through the Conduit and into the next Zone, the Efficiency will recommence draining.
  • Fixed Specimens beating the crap out of helpless players who are trapped in the loading screen when a Host migration occurs. Specimens will now be paused while you are in the loading screen.

Hotfix 22.18.7 (2018-04-25)
Sanctuary Onslaught Balance Changes:
Player experiences and data determined that enemy scaling was broken and not consistent with game modes outside of Onslaught. A more descriptive and in-depth read can be viewed here: https://forums.warframe.com/topic/950011-sanctuary-onslaught-difficulty-changes/

  • Removed Simaris line referring to 'comrades' when Conduit is closing to eliminate possibility of referencing other players when running Solo.

Sanctuary Onslaught Fixes:

  • Improved Infested spawns by adding more spawn points in the Onslaught Derelict tile (most commonly encountered in Zone 17 of this week's Elite Rotation).
  • Improved numerous enemy spawns to Onslaught Asteroid tiles.
