During the level where you have to find a member of the inner circle in a fancy apartment complex, go to the part where two cleaners are outside the window on the lift. Kill them both and jump down from ledge to ledge until you reach the bottom. Run along the edge of the building until you hear a shotgun blast from the inside and see someone flying out of a window. Kill the cleaner in his apartment but do not go in. Continue along the buildings edge for slightly longer and you will find an open window. Inside, is a memorial for someone.

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.
