Arctic Research Vessel Ostrica

Water beginning to pour into the Ostrica.

Ostrica formally known as "Arctic Research Vessel Ostrica" is a ship and combat location in Armored Core 3. It is found in the 1st Layer: Nature Area section of Layered.


Ostrica is a large frigate ship owned by Mirage that has sunk deep into arctic waters. The surface has since frozen leaving the ship almost entirely submerged. The reason given for its destruction is a fatal hull failure, most likely the result of having crashed into a glacier. Before the ship becomes fully submerged, Mirage asks The Raven to retrieve a valuable capsule on board and ensure the destruction of the on-board cargo. This suggests that the ship was primarily used to move important equipment and technology.

The location becomes a combat zone during the mission Recover Ship Cargo.
