Mission 29: Infiltration of the Cistern | Halo Alpha

This article is a stub. You can help Halo Alpha by expanding it.

“After defeating the Covenant forces at the light bridge, Spartan Palmer entered a cave UNSC Command designated the Cistern. Although a large number of stealth Sangheili were already in the area, Palmer moved forward, dispatching the enemy with skill.

Deep within the Cistern she found the structure's entrance -- large blast doors of Forerunner design, and from behind the doors, the origin of the signal. It was then that the UNSC scientists decoded the first part of the Forerunner transmission. It was a single word: "Palmer." They warned the Spartan that the structure seemed to know her name.”

Infiltration of the Cistern is the twenty-ninth mission of Halo: Spartan Assault.
