Level select and all challenges

Note: There are two side effects after using the level select cheat. First, stealth attacks no longer give you dog tags, which
means you cannot advance to a higher strike level. Get all the tags you need before using the cheat. Secondly, when you save
a game in which the level select code is used, the file is now marked with an "X" just before the time and date.

option. Go to "Gallery" and select "Play Movies." Go to the bottom of the screen to the last three movies
and you will find two bloopers with Wolverine and one blooper with the Wendigo. You get one blooper for each "Challenge"
that was completed.
* Tactical Decisions level
When you have to knock out the electric fence with the cannon gun, make sure you have full health first. Then, board the
gun, ignore the guards, and keep firing at the electric panel to the above left of the fence. Once it is destroyed, exit the
gun by holding Circle for a few seconds. You should have a little energy remaining, but the guards vanish once the gun is
exited, giving you time to use your healing factor.
* Increase feral rage
To increase Wolverine's feral rage, retract your claws and just punch the guard.
* Best approach and attack
When scouting for enemies use Wolverine's heightened senses. Once you have spotted an enemy, make sure you are close enough
to see them clearly, but not be spotted. If you watch them for a few moments in heightened senses mode, a faint hazy figure
of Wolverine will demonstrate the best approach and attack.
* Star Wars reference
Wolverine's voice is done by Mark Hamill, who played Luke Skywalker. For the Juggernaut battle, he fights a man with ultra
psychic powers wearing a helmet. Juggernaut uses the word "Force" every other line.
* Infinite score and dog tag loop
During Part IV: Grim Discoveries, after you have taken the elevator down into the cavern, you will face the Wendigo and
three soldiers. Instead of feeding the soldiers to the Wendigo, knock the gun out of each of their hands and lure them to
an open area. Next, position yourself so you can perform a level 3 strike on each of them simultaneously. You will be rewarded
with 150,000 points and a dog tag if the "Claw Slam" Strike is successful. Finally, if you run away from the elevator,
three more soldiers will rappel into the shaft with you. You can repeat the process as many times as needed for lots of points
and dog tags. Note: If you die you will have to restart the level. For best results, use the "Invincibility" cheat.
