Invincible Zombies Glitch
Play the game with two people, one being the Avenger and one being the Judge. After you both gain your second Edge (Smite and Burden) find a location with a lot of zombies. Have the Avenger use Smite and immediately after that, have the Judge use Burden to freeze the already dead zombies. When they unfreeze the zombies will be invincible.

Weapons Cheat
To receive some free weapons be in gameplay,have ur range weapon selected (ex: Martyrs dual handguns) and QUICKLY hit B, Up, Left, Down, Right, B, B. If you do this with a loaded game you will probably only receive the rocket launcher. If you start a new game you will receive a rocket launcher, a shotgun, a nice automatic, a chainsaw with no battery, and a flamethrower. It works, you must do it quickly and you can not do it with the analog stick, only the D-Pad.

Get The 'Good' Ending
Save at least 50 innocents during the game.

Special Orange Glyph
When entering the level MansionE1, otherwise known as the courtyard to the Mansion, hug the wall to the left as soon as you enter the area.  Walk along until you find a big gap.  Go in the little area, fight a couple bad guys and get the secret glyph which gives you added strength for the remainder of the game.

Catacombs Hidden Shortcut Tunnel
In the game of 'Hunter: The Reckoning,' there is a level called the Catacombs, which is the level right after you beat the big Teddy Bear.  Once you begin the Catacombs level, you go a little ways (after killing a few rats and some zombies) until there is a broken hole in the wall to the right (where more rats,  zombies, etc. await your presence).  Go in there and kill all the enemies, then there is nothing in it but an Orange Health Glyph in the center, a gun, and an innocent.  Kill all of the enemies in the room without using the Orange Health Glyph first, then shoot at the wall that is sort of straight ahead and to the left a little bit (almost like a 120° angle of a circle).  The wall will explode and a hidden shortcut will show a tunnel with little red Health Balls and blue Edge Balls in it.  Also, about half way through the tunnel, there is a Secret Orange Glyph that isn't just for your energy or edge meter!  Get there and find out what it does!
(Also, once completing this level while using the Hidden Tunnel, when the screen reloads for the next level, it will tell you that there is a Secret Button Configuration for invulnerability!)

Fighting Carpenter
When you are trying to beat carpenter, use martyr and make sure you have a flame thrower and rocket launcher. As soon as you get to him, use the rocket launcher to blow up the electric chair (about 6-7 direct hits) then switch to the flame thrower. Run like heck and spray him with the flame thrower when he stops to try and cut you. Takes a little while but i found this technique to be the most effective.

Easiest Way To Beat Slow Bosses
The best way to beat slow bosses like the teddy bear and the big monster with four legs is to use high fire power. They usually have help like monsters and ghosts, so get rid of them first. When they are gone equip a special weapon that is a gun. Run backwards and fire. To run backwards is to set the stick that is used to move the character back and the the aiming stick towards the boss. Keep firing the special weapons until its gone then use the basic fire arm that is unlimited. keep making it chase you while you shoot the crap out of it. Also keep your distance, the use a shockwave the can wrech you up.
