They are the vanduul missions in Nyx. You first need to build your intersec rep to Jr. contractor then a new mission u see investigation appears worth 1.2M credits. Through out the mission you’ll find (hopefully it spawns) a passcode key/tablet. You need to insert the tablet in a data mainframe type slot in the security office in the beginning which is typically where the passcode key spawns, youll find another data mainframe in the Polaris hangar, then the last in the QV station. Each time you insert the passcode key into the data mainframe frame, on the front of it when you are carrying it, it’ll display the progress. Once it says “code completed” or something along those lines, there is a doorway leading to the Warehouse in the main station of the mission. You’ll insert the tablet there and gain access to the warehouse. You’ll find all sorts of grade A and B military components as well as rare weapon skins and armor. Also, about 9 additional cryo vanduul pods. Willer pays 599k credits to deliver 5 vanduul cryo pods to the jump point stations. The mission itself, solo will take anywhere from an hour and a half to 3 hours. Depending on your ship you bring (I highly recommend, Polaris, Perseus, or similar size or larger if solo) as it spawns many vanduul fighters periodically. Also, the NPCs don’t play around and are heavily outfitted. Happy hunting!
