Ok, so after about 4 hours of yelling at my school 2 of my friends say he's russian, and i say that he is a Mix of Bosnian and Serbian. 
My thoughts are that, He speaks the mix of the languages, I CAN UNDERSTAND IT, Parents are Croatian, Very close Language,  And he says "The boys from the village" And i did some bad things in the war for bad people, He's Talking about the YugoSlavia break up 10 years ago(presuming the game is based in 2008) 
So, IS he a Russian or a Mix of Bosnian/Serbian? 
EDIT: and yes, I am fully aware that there was probably a topic but i want to make it clear to me.
