Yesterday's War is a story-arc episode, a chain of cross-faction missions in Star Trek Online. The player participates in the Temporal Cold War, where the Temporal Accords powers defend the timeline against its undoing by genocidal Sphere Builders, radicalized Na'kuhl soldiers, opportunistic Vorgon criminals - and ultimately the Temporal Liberation Front.

The Iconian War is preceded by the episode "Iconian War" and followed by "Future Proof."
