Critical Role's highly anticipated Campaign 3 finale is set to air next week, culminating in an eight-and-a-half-hour livestream event. Polygon reports the grand finale begins February 6th at 7 PM Pacific Time (10 PM Eastern, 3 AM UK time). Viewers can tune in via Critical Role's YouTube and Twitch channels, as well as their membership service, Beacon.
This momentous occasion concludes the captivating journey of the Bells Hells adventuring party, a saga that commenced in October 2021. While no immediate spin-offs are confirmed, Critical Role assures fans that the narrative within the world of Exandria will continue to unfold.

"This Campaign 3 finale closes one epic chapter of Exandrian history," states creative director and cast member Marisha Ray. "But the story persists; it's a simple page turn. I eagerly await the next chapter penned by our amazing, improvisational storytellers."
The conclusion of Campaign 3 doesn't signal a break in Critical Role's programming. A new Exandria Unlimited mini-series, comprising four episodes, premieres a week later on February 14th. Further shows and streams are also planned.
The commencement of Campaign 4 remains unannounced. Historically, there's a multi-month gap between campaigns (e.g., Vox Machina concluded October 2017, Mighty Nein began January 2018). Given this pattern, an announcement—or even the launch—of Campaign 4 around Critical Role's 10th anniversary on March 12th seems plausible.
