I'm just gonna run my mouth from sheer delight of how awesome this game is.
Did you know, when Ocelot gets you in a headlock, if you don't do anything, he kisses you? He goes '... Snaaaake~<3' in his creepy breathy voice.
If you fight the beauties and wait long enough, they go into white world mode and play the anime song on the iPod, they'll dance to it in the first 15 seconds or so. And if you take out the digital camera, they'll do up to 2 sexy poses. Awesome.
If you bump into people on the Mission Briefing as the Mk II/III, you'll get a camouflage of their face. I got one of Otacon, Colonel, and Raiden with his open visor.
If you want to know more in-depth stuff, just send me a message.
