@tranqbase:This article is incorrect. Maul has the lightsaber at this time period, and will do for another decade, as seen in Rebels. Son of Dathomir is still canon. I expect them to quickly cover it in the opening narration of the Mandalore arc.

@Emperorwon:Yeah, I get it from a narrative standpoint - as there isn't a Halo in the game - but from a marketing view you definitely want to call it Halo.

It's a cool bit of trivia but that's not what an easter egg is.

This is definitely not a new thing. Here's an article mentioning this 11 (!) years ago: http://uk.ign.com/articles/2007/05/17/uncharted-drakes-fortune-hands-on-2

"Instead of a health bar, the designers have used a pseudo-luck meter that drains the screen of color and amplifies the sound of your heartbeat as Nathan gets into rougher and rougher situations."
