Even though the weapon menu does not show them, you will still select it. Do not go past the second sink; if you do the scene will change. Stand by the bathroom entrance and throw a few grenades. You will see the Mona's body fly out of the shower. Because of the rag doll physics used in the game, you can move Mona all the way to the entrance with some well placed grenades.

Hint: Part 1, Chapter 4: Old woman:
When chasing after Mona, if you try to open the door of apartment A308, the old woman inside will issue a warning that she called the cops and they are coming to take Max away.

Hint: Part 1, Chapter 6: Kung Fu poster:
Go through the fun house until you reach Mona's hideout. Once inside, look around Mona's gym area and should find a poster of the famous Max Payne Mod "Kung Fu" by Kenneth Yeung.

Hint: Chapter 8: Bravura lives:
In Chapter 8 Continued, you will start on a flight of stairs. At the top, Vlad gives a little speech. Once you get through the electric door and into the hall where the 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 Max Payne) and that the Bravura is still alive in stable condition at the hospital.

Hint: Blowing Up: Explore the construction site:
In the Blowing Up level, when you get out to the support beams where a huge hole has been blown, jump down to the floor below you. Then jump down to the one below that. You can explore the ground levels. You can even walk through the giant spools.

Hint: Mike the cowboy:
The first time you see Mike (Vlad's friend), he will be helpful. Much later, you will 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.

Hint: 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.

This trick is useful when you reach the part where you have to finish Vlad off while he is on the platform. If you have an MP5 with a little bit of ammo, you can do this easily. In the beginning when he starts talking, back into the corner and get out the MP5. Zoom into the sticks. Do not shoot the middle. Shoot the edges of the sticks. In the beginning, you can cap off two. When the pause begins when he starts talking about giving you a sandwich, you can cap off two more. As the platform falls, if you are quick, you can cap off two more (from the sides). Run around that square a few times and cap off one more from the side. Then, run around again and cap off a couple more. Keep doing this until that triangular thing falls down. As soon as that happens, pull out the fully loaded Russian machine gun and finish him off.
 

After Vlad is shot off the platform and is on top of the lookout throwing Molotovs at you, save your rounds. When you hear pauses from the cocktails, Vlad is going for his gun. Once he gets to edge of the lookout so that he can shoot you, shoot his upper body with the M4 Carbine. Using any other gun will take longer.

When you reach the Vladimir Lem, you must shoot the stacks to make him reveal himself. He then starts to throw Molotov's at you. Do the stack shooting as fast as you can. If you use the MP5 with scope, it will be fast enough. Shoot the first three stacks, then use Bullet Time combo and shoot the other three. Move slightly, then shoot the last one. If you managed to do this, the floor will be only broken, and does not have holes. You can run around the structure that he is at, very close to the metal. When he throws the Molotov cocktails he will sometimes burn himself, and help with his own death.

Hint: Extra Uzi:
When you just enter the warehouse and see the little cubicle with the television inside, go a few yards to the right and climb on top of the boxes. Jump across and you will get an Uzi.

Hint: Extra pain killers:
At the start of the game, turn around and open the middle locker. Inside will be two bottles of pain killers to take whenever needed.

Hint: Fast reload:
Press [Bullet Time Combo], [Reload], and [Bullet Time Combo] again. Max or Mona will spin, and the gun will be reloaded.

Hint: Apartment memorial:
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.

Hint: Mad policemen:
In the chapter where Max is suspended inside the police station, go into the rec-room. There will be two policemen sitting on a couch watching television. Walk up to the television and shut it off. The policemen will make comments to Max and they will get mad at him, but will not actually do anything.

Hint: Help from the goonies:
In the chapter where you get some "help" by a few of the goonies, use the 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.

Hint: 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.

Hint: Theme song:
Play the piano with the dead body on top of it. Max will attempt to play his theme song.

Hint: Television shows:
If you are near a television, you can see a show that somehow reflects your life. The one that most copies your life is "Address Unknown".

Glitch: Part 1, Chapter 2: Man gets beat up by nothing:
You will start out on the bottom floor next to the room with the phone. Go up the stairs through the door to the next floor. Then, go up the stairs again to the next floor and meet your friend. To your left is a wood pen with a man laying in it. If you shoot the man or throw a grenade in the pen, he will begin to get beat up inside of the wooden pen by nothing.

Glitch: There Is No Us In This: Kill old lady:
In the "There Is No Us In This" level, the old lady that gives you the shotgun can be killed during the intermission sequence where Max tells her to close her door and not open it for anyone but the police. To create this glitch, throw either a grenade or a Molotov cocktail at the ground near the door as you are leaving. This will cause her to burn in the intermission sequence if using a Molotov , or get blown sky high if using a grenade. Also, if you do a backwards dive through the door while exiting and shoot the lady in the head as the screen fades to black, Max will be talking to no one during the intermission sequence. This means that there will be no body on the ground or anything else
