A countdown timer tied to Halo 5: Guardians has gone live on Tumblr. Shared by Xbox senior public relations manager Rob Semsey on Twitter, the timer is set to expire on March 21, 6pm Pacific Time (March 22 at 1am UK, 12pm AU). The page features the image of a bullet embossed with the word "TRAITOR", the hashtag "#HUNTtheTRUTH" and the Halo 5: Guardians logo. Details on what the reveal could be are sparse, but the game does not yet have a confirmed release date outside of Fall this year. Halo 5: Guardians was first revealed at E3 in 2013, and developer 343 Industries confirmed the Halo5:Guardians name in May last year.
