Efficiency: The means to maintain a Conduit.

Conduits: Portals connecting one Zone to the next.

Every two that are completed will provide a reward.

Zones: Equivalent to a 'Wave', 'Round', etc.

Players who have not entered the conduit before then will be extracted with their rewards. When a zone is complete, Simaris will open a Data-Conduit to a new and harder zone within his Sanctuary. Each enemy killed in the process will contribute to the overall efficiency, with Eximus enemies contributing more.Įvery zone lasts for 2 minutes and 30 seconds.

Upon starting the mission, players will have to enter a conduit and maintain efficiency meter against increasingly difficult enemies. 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. Players must complete The New Strange to access this game mode. The opposing faction of enemies encountered in each zone is also randomized on a per-zone basis. 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. Players are limited to one large room from a random tileset in every zone. 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. Sanctuary Onslaught is an endless game mode introduced in Update 22.18 ().
