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.

agents are and have killed them, go over to the television in the corner and turn it 
on. A news report will start, mentioning the gang violence from 2001 (the original

have to fight him. To avoid that fight against Mike, let him take care of every 
mobster in Ragnarok. He should get killed. If this does not happen, after the final 
Mob fight, kill him just after the intermission sequence that presents the names of 
Vlad and Vincent. You should be able to take care of three to four enemies without 
his help.

following tricks. When they shoot their guns, stay behind them. Secondly, let them 
take care of all the cleaners and masked men (which will lead into the following 
tip). If there are any remaining, have an automatic gun ready and cap all of them. 
One of the goonies will be reminded of your name being Max Payne and they will 
turn on you. 

Surviving in Dead Man Walking mode: 
Choose the first Dead Man Walking level. You will start behind a van. When you 
just enter the level, quickly get the painkillers and go behind the van where you 
started. Use your camera with intelligence to see when the enemy is coming. 
Quickly enter slow motion and kill him with a quick weapon. Then, repeat the 
procedure. When they die, go in bullet time and get the weapon. When the enemy 
number starts growing, use your grenades and Molotovs. Note: Bullet time, and 
not shootdodging, is very essential to stay alive in the first place. Use it wisely.
