Sanctuary Onslaught

Sanctuary Onslaught is an endless game mode introduced in .
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===
*Zones: Equivalent to a 'Wave', 'Round', etc.
**Every two that are completed will provide a reward.
*Conduits: Portals connecting one Zone to the next.
*Efficiency: The means to maintain a Conduit. Once efficiency reaches zero, the run will be over. The deeper the player progresses into the Sanctuary the faster their efficiency drops and less efficiency is gained from enemy kills, capping at Zone 16.
**Efficiency Stimulus: Pick-ups which increase the player's efficiency by 10%. The number of Efficiency Stimuli that appears starts at 4, which gradually decreases the deeper the player progresses into the Sanctuary, up until after Zone 15 after which they will stop appearing.
===Rules===
Simaris has his own rules within his sanctuary, as he seeks to produce an accurate experiment. These are the following rules:
*The Gear wheel and Specters are disabled. Emotes can still be used.
**However, Helios can still take scans if the mod and Codex Scanner charges are equipped.
*Specimens do not drop Mods or Resources in the Sanctuary but will still drop Health Orbs, Energy Orbs and ammo pickups.
*Storage Containers do not appear in the Sanctuary.
**However, locked lockers may appear depending on the tileset, and can be opened using or to acquire orbs and ammo pickups. Lockers do not drop resources or mods, but, unlike specimens, they may yield Affinity Orbs and sometimes an invisible Ayatan Star.
*MOA Cabinet Spawners can appear in their appropriate tilesets, producing fragile allied Shockwave MOAs if hacked.
**Despite gear restriction, Ciphers are still available if equipped before starting, visible only while hacking a cabinet.
*Each conduit entered/zone advanced removes current buffs, active Warframe abilities, combo multipliers, and resets Energy to the respective initial level, as well as restoring ammunition back to 100%.
**Additional base energy contributed by a Warframe's spare mod capacity will not be accounted for.
*** works however.
** will lose 4 Mutation Stacks upon entering the Data-Conduit.
** will lose approximately 300 Rubble upon entering the Data-Conduit.
**'s damage growth decreases by 30% upon entering the Data-Conduit.
**However, ' battery will not drain upon entering the Data-Conduit; the same goes for 's restraint meter.
*Instead of dropping normally, Convergence Orbs are granted automatically at the beginning of each zone after the first. The Convergence Orb Boost scales in multiplier up to 16x.
*There is a 20% chance for a random environmental hazard to appear in a zone.
*Enemy level starts at 20-30 and gradually increases to 80-100 beyond Zone 15, 110-130 beyond Zone 20, and 130-150 beyond Zone 25.
*Weekly leaderboards are available based on overall score for both Sanctuary Onslaught and Elite Sanctuary Onslaught.
===Elite Sanctuary Onslaught===
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.
* A Rank 30 Warframe or a Mastery Rank 30 player whose Warframe has been polarized once is required to play Elite Sanctuary Onslaught.
*Enemy level starts at 60-70 and gradually increases to 150-180 beyond Zone 15, 200-220 beyond Zone 20, and 250-280 beyond Zone 25. Increased efficiency drain caps at Zone 15.
*Abilities become disabled if used in quick succession:
**First abilities are disabled for 8 seconds if used six times within 2 seconds.
**Second abilities are disabled for 8 seconds if used four times within 10 seconds.
**Third abilities are disabled for 10 seconds if used four times within 10 seconds.
**Fourth abilities are disabled for 15 seconds if used twice within 10 seconds.
**Channeled abilities only count when turned on; however the cooldown timer only begins once the ability is turned off again.
**Injected abilities are disabled using the conditions applicable to the new slot they occupy.
*Zones 1-5 only spawn 2 Efficiency Stimuli (Stimulus spawns in Zone 6 and beyond remain unchanged).
==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.
*2, 10, 18, etc. Zones = Rotation A
*4, 12, 20, etc. Zones = Rotation A
*6, 14, 22, etc. Zones = Rotation B
*8, 16, 24, etc. Zones = Rotation C
==Tips==
*'s , 's , 's , or 's are effective at clearing out the entire map of enemies.
**'s scales very well throughout Sanctuary rounds. Its subsumed version is useful for lower level rounds on other Warframes.
