Map of Chasca.


In the Matano system you’ll find the planet Chasca, where the assignment UNC: Colony of the Dead takes place. In the southwestern corner of the map you’ll find two Civilian Structures and a Science Facility, which house a variety of Husks. The meat of the aforementioned assignment largely consists of clearing the Husks out of these structures.

Other than that, you’ll find a Prothean Pyramid in the southeastern corner of the map, near which you can score a Prothean Data Disc.
