Unlock Bonuses, Earn Cheats 
Earn a 3-star rating on any level in order to unlock a bonus piece of artwork. As 
an added bonus, each piece of art has half of a code on it. Combine the left bonus' 
code with the right bonus' code to get the cheat. Cheats can be entered on the title 
menu. 

God mode:
Successfully complete the game under the Fetish difficulty setting, then press Down
(2), Circle, Up, Square, Triangle, Square, R2, Up(2), L1, Triangle at the title 
screen. The message "God Mode" will appear at the bottom of the screen to 
confirm correct code entry. Note: The game cannot normally be saved while this 
code is enabled. 

Use the following trick to save the game while in God mode. Enable the God mode 
code, then finish a few levels with a three star rank or higher until you get a bonus 
level (Hard as Nails, Brawl, ect.). Then, play one of the bonus levels, die, and quit. 
This will reset the codes you enabled. Next, play any easy level and save at one of 
the check points. You will keep all the stars that you have earned with the cheat 
codes.

Cheat mode:
The following codes have no effect until you complete the both levels with at a five 
star rank under the hardcore difficulty setting to unlock them. Each code has two 
parts, each of which are unlocked by a specific level (for example, at the end of 
level 1 and level 2 with at least a three star rank). 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.

Slash master 
The whole point of Manhunt is to create some gory footage of peoples death 
without them knowing your doing it. Basically 'silence is violence' so it is no good 
you smashing someones head open with a black jack or a baseball bat. You need 
to slash them open and create gushers of blood which will stain the walls red and 
maybe just maybe hell itself will spit you back out. So always use a knife or some 
implement of cutting to kill the hunters.

Nail gun execution 
Sneak up on a hunter while having the nail gun equipted. wait a few seconds and 
then the execution mark should appear. press square and x and he should grab 
the hunter and repeatidly shoot him in the head, regardless of how much ammo 
you have.

Full Level Completion 
To get full level completion you must must execute every gangster in the chapter 
in the most vivid way(Until the target goes red) This is a very helpful method for 
those MGS mad-fans! Know that this doesnt apply to bosses in the level where 
there is a cut-scene.

Unlock Bonus Games
To unlock the bonus games, you have to earn three star ratings on groups of five 
levels. The games are unlocked thusly: 

Hard as Nails: Get three stars on each of levels 1-5. 
Brawl Game: Get three stars on each of levels 6-10. 
Monkey See, Monkey Die!: Get three stars on each of levels 11-15. 
Time 2 Die: Get three stars on each of levels 16-20.

Alternate title screen:
Successfully complete the game, then press L1 + L2 + R1 + R2 at the title screen 
to hear a backwards message being whispered. Note: A new segment of 
whispering can be heard each time the buttons are pressed. 

Killing Your Enemys
Here is a quick tip on the best way to kill your enemy. First off, everyone should 
know how to snuff the enemey (you do this by quitely killing your enemey 
quickly). This is done by sneeking behind the enemy and holding L1 to target. 
Once your target/aim has gone white, hold it for longer til it turns red. This will 
provide a quicker more powerfull execution.

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.

Mouth of Madness level: Bonus item: 
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. 

Easy five star rating in hardcore mode:
Successfully complete the game in Fetish mode. Then, enable the "God mode" 
code and play the game in hardcore mode. You will be invincible. Execute 
everyone. If you are seen, run into the shadows, execute him, then run through 
the level. 

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.
