Successfully complete game and unlock the Princess Heart costume and the Heather Beam weapon. The Heather Beam is a special weapon which you can only use if Heather or Cheryl is not holding any weapon. Defeat all monsters and Bosses using only the Heather Beam. Note: The "Monster defeated" counter should read 0 kills.
Kill all monsters with any weapon except melee ones, preferably the unlimited sub machine gun (a special weapon).
There are multiple areas in the game where special death scenes occur for your character if you trigger them:
In the hospital, allow yourself to be killed by the nurses. The screen will go black, and then it will show Heather lying on the ground, as a male doctor zombie shambles up, grabs and widely spreads her legs, and drags her off into the darkness.
At the final area, after Claudia kills Vincent and the exchange between Heather and Claudia ensues, equip a weapon and attack Claudia with it. Heather will then begin to bleed out and birth the "God". This is not really an ending, as it counts as a "Game Over", but is a gruesome ending nonetheless.
While in the subway, hop down onto the tracks and run all the way to the end of them, into the tunnel. Heather will be run over by the train, accompanied by nauseating sound effects.
When on the train, simply turn around and exit through the door in the rear of any car. Heather will be on the very end of the train. If you move forward towards the edge, a first-person cut scene will occur in which Heather falls from the train onto the tracks, and dies.
There are other death scenes located in specific areas throughout the game. Look for areas that seem significant (locations from previous games, for instance) and allow yourself to be killed.

Subway: Vengeful ghost
When initially reaching the subway station, look for a cluster of vending machines for coins and tickets. On top of one of those machines is a newspaper telling of a man who was killed, presumably by accident, by a train. Later, once you begin descending levels, you will come across a stairwell that has an occult magazine lying on the ground. Read it, and it will describe how the ghosts of those who commit suicide or those who died by accident often come back to haunt the places of their death, and will either come to people for help or take revenge on them. If you read both of these articles and descend the steps, Heather will walk down to the subway track, and a small intermission sequence will ensue which has a ghost push Heather onto the train tracks. You must turn around quickly and climb back up, or you will be killed by an oncoming train. Note: That this occurred in the Extra New Game mode, and may not happen the first time through on Normal Game mode.
Order of tarot cards at the last door of the game
Arrange the cards as follows in the normal action and normal riddle difficulty settings:
Northwest position: Eye Of The Night
Northeast position: Moon
West position: High Priestess
East position: Fool
South position: Hanged Man
Arrange the cards as follows in the hard difficulty setting.
Northwest position: The High Priestess
North position: The Eye Of The Night
Center position: The Fool
East position: The Moon
Southwest position: The Hanged Man
The riddle is a problem with Roman numerals. The Priestess is number II (2) as read on the book about tarots. The Eye Of The Night is XXII (22). The Fool is 0. The Moon is XVIII (18). The Hanged Man is XII (12). Look in the book of drawings to see that XVIII can stay only in the east position (the last letter is I instead of L); XII is only in the southwest position; II is only in the northwest position; 0 and XXII have two places where they can stay. Swap them until you find their correct place.
Kill 333 enemies. Playing through the game several times will achieve this. Note: Wear the Transform costume to change the Heather Beam into the Sexy Beam.
Successfully complete the game under the hard action and hard riddle difficulty settings to unlock the "Life Bar" option at the extra options screen.
Never get tired
Equipping the Princess Heart or Transform costume will make Heather run long distances without getting tired. This is also useful for the Heather Beam weapon, since it depends on how tired Heather is.

You can find a shotgun is in the subway and a machine gun in the hospital. The best weapon for last battle is the katana.
