So did I miss something or is there a lot left out? I have only played this one and not the prologue thing or brotherhood. But here are some questions that left my confused.

So we got the guy with the hood and the guy with the broken nose.

How did the boss (snake face) of hood guy get killed? And why is hood guy in the hospital? Last time I saw them they were getting shot by broken nose sniper guy but he left after killing the one dude.

These was a lot mentioned of the american mercenary victor or whatever but I never saw him, probably missed something here.

Please help me understand :p Thanks
