Events and Operations

Operation: Sling-Stone victory diorama

Many Tenno lead a solitary fight, performing actions of sabotage and harassment with no backup. Other Tenno operate in small cells of comrades, or in larger clans with a shared purpose or vision. Yet sometimes, a threat arises to loom over the whole Origin System. In these times of world-changing battles, the Lotus calls Tenno from all over the System to participate in a collaborative effort, with a common objective, against a common foe. Sometimes the Tenno succeed, and sometimes they fail. Sometimes, Tenno disagree on the correct course of action, and must contribute to competing interests. No matter the execution, these events or operations bring the Tenno together like no other occasion, and are responsible for the state of the System as it exists today. Thus, we have catalogued them, for the inquisitive Tenno who wishes to study the history of how these things came to be.

These events are divided into the five major phases of Warframe history, as determined by us at the Orokin Archives. Dates and information are for the PC version where applicable.


There are also smaller-scale events not requiring full Operations. Tactical Alerts are smaller events without leaderboards, usually taking place over a weekend, always rewarding a Stratos emblem. Every Stratos emblem earned after the first changes the design of the emblem. Tenno who have completed many Tactical Alerts have elaborate Stratos emblems to commemorate their achievements. Special Alerts are miscellaneous Alert missions that usually have a small amount of associated lore.
