XDefiant, the upcoming FPS from Ubisoft led by former Call of Duty boss Mark Rubin, has been delayed in what is the latest chapter of the game's long and bumpy road to release.

In a social media post, Ubisoft said it hoped to release XDefiant by the end of March. However, there are "still some improvements" the studio has to make before it's ready. Right now the focus is on an upcoming 12-hour stress test for the game's servers, and Ubisoft is inviting its early access players to hop in and try to put the servers through their paces.

After this process, Ubisoft said it expects to be able to lock in a public release date and begin to discuss XDefiant's post-launch content plans.
