Excalibur Prime is unique among the Primes of Warframe. While not every warframe in the game currently has a Prime form, Excalibur Prime is the only one that is completely inaccessible to anyone who was not a supporter of the game some time ago. So it makes a certain amount of sense that the third and final teaser trailer for the game ends on a shot of Excalibur Prime lying in the ash… only for a surprise moment at the very end of the video after the text vanishes.

As with the prior set of videos, it’s unclear what this means; it may very well mean nothing other than that Excalibur Prime is an important link to the past of the game and hints at events coming full circle with this reveal. But you’ll find out soon enough if you’re a fan and cannot wait to learn what will be revealed at TennoCon 2025 on July 19th. Onward hie, indeed.
