Nearly a month after its release on PC, the latest Warframe update is now live on both the PS4 and the Xbox One as well. I can only imagine that the holidays slowed down the certification progress, hence the delay. That or Digital Extremes just wants the PC version to reign supreme (who would blame them).
No matter, now PS4 and Xbox One users can check out the new content, including the Nidus Warframe, and the storyline followup to the War Within.
