In the Paramount+ sci-fi drama, the galaxy is on the brink of destruction, so Master Chief Petty Officer John-117 (Emmy-nominated actor Pablo Schreiber) leads his teams against an alien threat known as the Covenant. When the first season debuted in 2021, it arguably paved the way for additional video games to be adapted into television shows, like "The Last of Us" on HBO, "Twisted Metal" on Peacock and the upcoming "Fallout" on Prime Video. New episodes of "Halo" begin streaming Thursday, Feb. 8 on Paramount+.
