Shipwrecks are sites found on planetary surfaces that consist of one or more derelict humanships or SRVs that have crashed, been destroyed, or been abandoned, along with scattered Commodities and Materials. Some have been located by following transmissions picked up by nearby Listening Posts, which usually involves finding a trio of related Listening Posts and combining their fragmentary data logs to determine the shipwreck's system, body, and surface coordinates. The locations of others have been randomly distributed to commanders by anonymous sources via "Tip Off" messages, which contain full details about the site as well as a single-use key that will allow valuable Data Packages from the Ship Data Core to be downloaded. Many shipwrecks have uplinks that can be scanned with a Data Link Scanner to retrieve text and audio logs recorded by the ship's crew or owner which shed light what caused the ship to crash.
Crashed Anaconda with Thargoid Sensors nearby. Likely associated with the Neo-Marlinist Liberation Army, which used corrosive enzymes obtained from Thargoid tech in its explosives and built bomb-making facilities in the system.
Likely smugglers, as the wreck is surrounded by narcotics and personal weapons.
Col 285 Sector NA-S b19-6
Crashed Eagle MkII. Tip-off site with Ship Data Core and commodities.
Shipwrecks are not to be confused with generic Points of Interest which appear on planetary surfaces. Points of Interest appear randomly during surface exploration, and are neither static nor persistent sites. One way to determine if a crashed ship is a true Shipwreck or a temporary Point of Interest is to see if the site has a persistent nav point which can be selected from orbit.
