Wait so 46 is the ending...what a twist

I'm confused so I ended up skipping the Quiets ending mission and did 46. I learned the secret about big Boss but is that the same ending if I did the Quiet mission

How many endings are there outside of mission 51 with Eli ending

 

David Hayter finally plays the game MGS5 for the first time.

Alright, I put it off for years... But Laryngitic Snake aside? This game's pretty fun. (Shakes fist at sky) "KOJIMAAAAAA!!"
