Cheat Codes
First you must go to the game folder and find the file named nwn.ini Now open this file in Notepad and go to the Game Options section, and add the following:
Debug Mode=1
If you are going to edit the characters, open the nwnplayer.ini file and add these lines:
Single Player Enforce Legal Characters=0
Single Player ItemLevelRestrictions=0
This allows you to play past the module you're on.
Now save the file and start the game. During the game hit the tilde (~) key to bring down the console. Now type DebugMode=1 . Cheat mode is now enabled. Cycle through the codes with the tilde (~) key. Use any of the codes below. If you get a message that says Enter Target Mode Appears, click on the character you'd like the code to affect.
Hit pause, now press down, right, down, right, left, left, up.
Rage Attacks
You must get a supersmash before you can use Rage attacks. You also need 2 or more blocks of rage to use it.
Use any config on any plane
Select a plane in offline mode with a configuration, then hit close. Fly the plane then exit. Now select a different plane and instead of clicking close, click fly. The config on this plane should be the same as the previous one.

Get Infinite Viewtiful Points
At any of the Power Conductor Stations (two orbs on top of small towers that light up when hit, the first you come to is in the sewers of the second episode.), stand in the middle but closer to one than the other. Zoom in and kick to hit both Towers, and the one you are closer to will light up before the other one. Kick again (while still zoomed) to finish the chain and have the towers reset. If done correctly, the conductors will not activate and the two bottom lights will be kicked on, you will also get 100 Viewtiful points for the move. Repeat this process to continually gain 100 points for as long as you want.
Listen to Hidden Tune
When you're at an area with no enemies around, you can try out this neat (but useless) trick. Take out a bomb and hold the kick button (the same button used to take the bomb out). Joe will then juggle the bomb and whistle a part of the Mario theme tune. If you jump up in the air and do the same thing, and Joe will whistle a different part of the Mario tune. You have to listen closely to hear it.
Kill the Shark in under a minute
To easily kill the shark simply hit it like hell whilst zoomed in when he is not attacking and then when he attempts to eat you turn slow motion on and zoom in, then simply spin kick whilst he is trying to eat you, and he won't be able to grab you in his mouth and when this is happening you are kicking hell out of his life bar.
