Which ending do you prefer?

[BigBrother]

The Meryl ending is definitely canon - it's referenced at the beginning of the Tanker that Snake got the optic camo through Mei Ling, and I also took the scene with the bandana in the Big Shell as another pointer. Iirc it's referenced that the Colonel made arrangements for survivors to be rescued from Shadow Moses, which is how Otacon got out - I don't think Snake would've left him to die. I also recall Otacon volunteering to sacrifice himself to open the security doors remotely...

In regards to Meryl in MGS4 and how she's like that....nanomachines bruv. Christ was MGS4 a mess from a story, narrative and character perspective...
