Secrets  -  10 hidden lives  -  In the area where the cheese farm is. Jump around towards the back wall and the B light bulb will appear. Conker will turn into an anvil, break a wall and the tail there gives 10 extra lives.

Skills - The following are the skills of each character:

Demolisher: Berserk, Spray Can
Grunt: Self Heal, Spray Can
Long Ranger: Intravision, Spray Can
Sky Jockey: Spray Can
Sneeker: Cloak, Feign Death, Spray Can, Disguise
Thermophile: Self Heal, Spray Can

Autosave - Go through a tunnel that shows the loading screen to autosave your game.

Faster cloak for Sneaker - While playing as the Sneaker, equip your cloaking ability in a multi-player match. While holding your saber, jump down from a high area (for example, the beginning of the Beach Dead map). About half a second before you hit the ground, press X to activate your cloaking ability. If done correctly, your character should hit the ground fully cloaked, and you will not have to wait to activate it on the arm panel and flash. This is particularly useful for jumping into battlefields to surprise the enemy.

Disappearing tank - Get in the tank and click the Right Analog-stick. Then, hold L + R and click the Right Analog-stick again and you will be able to shoot without the tank. However, you cannot move unless you click Right Analog-stick twice.

Shotgun light - Once you get the shotgun when you open the level by the barrel to the zombies, you can have a light on your back. When you shoot, silver bullets will appear. To do this, equip the shotgun and do a circle looking in front of you. Shoot, then press B immediately. Keep doing a circle with the Left Analog-stick. This may require a few attempts.

Swim without water - In the Barn Boys level, go to the side of the barn where it slightly starts to curve downwards. Then, go to the brick pillars. Stand against it, then walk forward slightly (make Conker tip toe). You should hear a splash. The camera will glitch and show a view of the big bucket on top of the barn. If you move forward, Conker will either jump or fall from the sky.

First person jumper - While playing a game in Story mode, you can jump and hover while in first person mode (hold L). You are not supposed to be able to move Conker at all when in first person mode.

Banjo-Kazooie reference - On the screen that has the Xbox Live and Co-Op options, switch to the options part. Look above the fireplace to see Banjo's head above two crossed muskets.

Grabbed By The Ghoulies reference - At the beginning of the game, select Game 3. The doors in the background should open to reveal Cooper, the main character in Rare's first Xbox title Grabbed By The Ghoulies, huddled over a toilet.

Killer Instinct reference - While playing a game in Story mode, allow the game to idle. Conker will take out a handheld Xbox and start playing Killer Instinct.

Tech Deck reference - In the Mugged level when you are attacking the cavemen on lava boards, they look like Tech Deck characters. The first one is Spike, the second is Dr. Digit, and the third is Lenny.

War movie and game references - There are some multi-player maps that have names that are similar to war movies or video games:

A Bridge Too Narrow: A Bridge Too Far
Beach Dead: Beach Red or Beachhead
Castle Von Tedistien: Return to Castle Wolfenstein

The Assault level (demo version) - When you get off the boat, it is very tempting to race ahead and get past the gun turrets. However, you can hide behind the tripods and wait for them to reload. Then, make your way to the next one. You may be able to skip but it is not recommended. Then, just kill the Tediz's for the rest of the level. At the end you will find your commanding officer in an electric chair. When you get there, you can pull two different levers. One lets him go, and the other kills him.
