2. Master Chief
And now, an acknowledgement from Rockstar that they know their key audiences, and that they trust them to be able to uncover little gems by simply spending enough time in the game to explore every single nook and cranny of the map. If you head to the cleverly named Cinema Doppler, which is of course a thinly veiled homage to the Chinese Theater, you'll find an impressive Master Chief knock-off, reduced to selling pictures of himself outside of the venue with tourists. It's probably not the outright fun-poking at Halo it might seem, but it's still a nice little egg for anyone wandering around that area of the map. You could even knock him out and defile his sleeping body, as this Youtuber did... Strictly speaking, this is only one of two known appearances of Master Chief in the game. The other is of a slightly smaller version of the character... This again is just another of the many Easter eggs hidden in the game, another of which celebrates Claptrap from Borderlands 2, and which would be extremely easy to miss, if it weren't for the ridiculously eagle-eyed Easter egg hunters on the net...
