The titan expedition wrapped up end of march 2025, so those rewards aren't available anymore. For about six weeks players could earn some pretty exclusive stuff, including the wraith living ship, custom ship parts, and special posters. Nothing confirmed yet about bringing this one back, though some older expeditions do get reruns occasionally. Best bet is keeping an eye on community announcements if you're hoping for another chance at those rewards. A lot of players track these events through the official channels, since timing is everything when it comes to limited-time content like this.

Remember to watch the announcements section, since that's where they post expedition schedules and return dates first.
