i am at the part where after you assignate nikoladze the whole place is looking for you and i went through that huge dinner table room and into the hall way with two doors facing the same way. and i look with my optic cable and there is two dudes on the other side of either door with guns pointed straight at me. i cant get through those doors because as soon as i open them they kill me. i dont have much life of bullets, could somebody please tell me how to get past this part!
