Finally I’ve done this… what a stress…
Metal Gear Solid 4
difficult: Big Boss Extreme
no alerts
no kills
no continues
no rations, regains or other curative stuff used
no non letal ammo bought from Drebin
time < 5 hours (3:53:42!!!)
A pic from my TV…
It gave to me the Big Boss Emblem (in the picture), the FaceCamo of Big Boss (Solidus…) and a lot of other things… 
Thanks to this guy Tyndis for his precious and amazing videos on YouTube!!!

I am on act 3 of my attempt. Just got past the 1st half of the motorcycle chase. Damn that part is hard. This is my 4th play through. I got the Fox Emblem and a few others. I wish the PS3 gave tropies for this. I doubt i would ever attempt this again.
