Defeating Vlad
As the battle starts, equip your MP5 and enter the scope mode. Look above the Vlad's location to see four cylinder-like wooden pipes holding the sitting-place (the square-like place that Vlad is on). Shoot the wooden pipes and they will fall out of their places. Remember to dodge Vlad's dynamite. As you shoot the last pipe, the sitting-place will fall down but Vlad is still out of your view. Look up again to see four more wooden pipes that are preventing a large pillar from falling down. Shoot the pipes out and the pillar will fall down, making Vlad move aside avoiding the pillar. After that Vlad, is in your view. Equip any desired weapon (M4 Carbine recommended) and finish him off. Note: Beware of Vlad's molotov burning bombs. When Vlad is on the platform, after he throw the cocktail and says "I haven't forgotten about you Max", look up above the platform. Then go into Bullet Time and shoot the wooden poles. After that the platform falls but he is still hidden, look up again and shoot the wooden poles again. Do not forget to go into Bullet Time. After the big spike falls, go into Bullet Time again. Vlad will pop up and try to shoot you, leaving him open. Use the MP5 to get a more accurate shot. When you fight Vlad, he throws dynamite into the room. Go back in the room to find ammunition for the MP5 and M4.
