Max Payne Cheats

On Part I: Chapter 2, you can cause the rats to war amongst themselves. Use the developer command line cheat and give yourself a grenade (<F12> then ''getgrenade'' in the console) at the start of the level. Toss it in the gap of broken titles after the initial level_start camera panning. This will cause the mission objectives to change to ''I had declared war against the rats''. As you progress through the level, you will come across the two factions of rats -- WITH DESERT EAGLES! Shoot at one of the ceiling lamps that's off at its base to make it fall, causing the start of the war. If your group of rats wins, they will join forces and follow you through the rest of the level. If the other rats win, they'll turn their remaining forces on you.

On Part I-Chapter 3, there is a door that you can break down (just before the toppling boiler). Go through the door and out a window. After following the bloodstains on the ledge, you'll come to another window to go through after bashing in. Lots of goodies here, and also a body with a stake in its back on the floor with the letters ''BUFF'' drawn next to it in blood -- a little tip of the hat to a famous vampire slayer.

In the training level, look closely at the sign on the TAR CAFE (it's near the Police Mobile Arrest Centre on the street). It says:
''World's Best Since 1964
615 ALL YOUR BASE ARE...''
