Halo TV Series LEAKED!

Ahead of Xbox’s 20th Anniversary event – which is likely where this video was meant to be debuted – DexertoSpartans (below) reported that a teaser for the show was running on Facebook advertising.

The teaser includes a series of extreme close-ups of Master Chief’s armour, showing the live action versions of his gloves, 117 insignia, and the back of his head as his helmet’s put on. That’s followed by the voice of Cortana saying, “Hello, Master Chief,” alongside a shot of the front of the helmet.
