1. Your Reflection In Any Mirrored Surface
https://www.youtube.com/watch?v=SW8CrAQ-r1Q There's a good reason mirrors aren't a staple of the environment in MGS V; they actually give away the game's big final twist. To delve into spoilers, the 46th mission, Truth, reveals that you're Big Boss in name only. Instead, you've been playing as the medic from the crash at the close of Ground Zeroes, albeit with facial reconstruction surgery making you the perfect stand-in for the real Snake. As such, if you look to either the side of the ACC during the evening - or get close to the glass exterior of the chopper whilst on Mother Base - you'll see your created character from the very beginning of the game staring back at you. This element of duality plays into the final reveal as Venom stares at his own reflection, listening to the words of Big Boss describe his role from here on out. It's a haunting moment, but one you could actually cotton onto earlier, had you found a suitably shiny surface to squint at. Are there any awesome secrets we missed? Let us know in the comments!
