Play on the "Hardcore" difficulty setting and either do lots of gruesome executions or get lots of kills, and finish the level as fast as you can. Also, be stealthy and avoid confrontations as much as possible. Fist fights or ruined stealth opportunities make you lose time and lower your ranking.Opening gates
When on a level that requires a crowbar to open a gate, just shoot the lock with a gun. You can now walk through the gate.Killing Piggsy
To finish off Piggsy, after you stab him three times go up the stairs and lure him onto the grate at the top level. The grate will bend the first time and he will run away. Lure him back upstairs and onto the grate for a second time and he will fall through. Make sure that you are also not on the grate or you will suffer a similar fate as Piggsy.Early sawed-off shotgun in Born Again level
After you are let out of the execution room, you will soon find yourself in a basketball court where you have to defeat several gang members that are sent out after you. There is an opening in the fence around the court where you will see a posted sign reading "Vote Congressman Matthew R. Dione for Willington Mayor". Under the sign in the tall grass should be a sawed-off shotgun.Bonus item in Mouth Of Madness level
In this level, you must kill the smiley hunter on the tower and bring his body to the guard room. Kill the hunter on the tower and make sure to cut off his head. However, do not bring his body to the guard room (just his head). An intermission sequence will show you entering the guard room with only the head. Starkweather will say "For bringing this head I will leave you a little gift in the next location". Look around for the unknown item.Gruesome view
When a victim is on the ground begging for his life and before you finish him off, hold R3 and start attacking. The camera angle will then show a partial close-up view through the eyes of the victim, with you swinging away.Exploding head
In many instances a foe can lose his head in one of the death animations, such as baseball bat level 3 or wire level 3. If you smack a downed opponent in the head, their head will basically explode. If you have severed their head prior then go to smash it in, it will still explode as if the head were still attached to the body.Transforming head
Hit a save point with a throwable head with you. If you die, it will become a head with a bag wrapped around it.Floating chainsaw
When you kill Starkweather and Cash puts the chainsaw through his head, Starkweather's corpse falls over. Cash will then put the chainsaw in his stomach. However, sometimes he does not directly get it on his body and you should see the chainsaw floating in mid-air.Grand Theft Auto 3 references
Towards the end of the game, the journalist on television doing a news report about Starkweather mentions Carcer City's police chief Gary Schaffer and his involvement with Starkweather. In Grand Theft Auto 3, on the Lips 106 radio station, a news report states "In nearby Carcer City, police chief Gary Schaffer's was cleared of corruption charges." It then continues to say "Let's hope those missing witnesses turn up soon."Grand Theft Auto: Vice City references
In the journalist's apartment, in the one room is a blue and white shopping bag with the words "Gash" written on the front of it. This is the same name of a department store in the North Point Mall in Grand Theft Auto: Vice City.
In the Fueled By Hate level go to the junkyard. The car crusher and its surroundings are the same from Grand Theft Auto: Vice City's junkyard.
In the View Of Innocence level, on the second floor in one of the shoot out locations, look for a little counter with the words "Tarbrush Café" and a little picture of a coffee cup. The Tarbrush Cafe is the location where Tommy and Lance had to destroy in the Cop Land mission in Grand Theft Auto: Vice City.
The following codes have no effect until you complete both levels with a five star rank on the hardcore difficulty setting to unlock them. Each code has two parts, each of which are unlocked by a specific two levels (for example, completing the Trained to Kill and Border Patrol levels with a five star rank unlocks the "Invisibility" cheat). When this is done, one half of a code will appear at the bottom of the image that is now unlocked in the "Bonus Features" menu. Once both halves (images) are unlocked, that specific code can now be activated in any level in the game.
