| CluckShot |
| A Boom shot that fires exploding Chickens . 1. To start off, you
re going to need to play through Act 4 Chapter 1 on Insane. So this means you either have to beat the game once already, or you
ll need to play coop with someone who has beaten the game once. 2. Go through Act 1 without touching any of the ash bodies. Doing so will get you the secret
Respect For the Dead
Achievement once you arrive at Griffin
s Hideout and enter his secret weapon stash. More importantly though, it will give you access to this little chicken to the right with a pirate hat. Press X to interact with the chicken to cause it to explode, as if to officially kick off our easter egg hunt. 3. Now, play through Act 4 Chapter 2 like normal. Just make sure that you find two special ammo boxes that fall off a cliff as you approach them. The first one can be found at the start of the act on top of a car. The second can be found at the end of a railroad track in the underground section where you
re attacked by Polyps. 4. Now continue playing as normal until you reach Act 4 Chapter 3. After you head past the lift and go through the barbed wire, you
ll come to a fight with a bunch of Formers. Make sure to take them all out and then look for a stack of objects with another ammo box on top. Kick the stack to cause the ammo box to fall. Wait for a second and you
ll spot your
air support.
One specially made Cluckshot for every member of your party! |
| Dom's Beard For Everyone |
| This Easter Egg will make every character in the game have Dom's beard, during gameplay and cut-scenes. Even NPC's will have it. To get it, you MUST be playing on Insane difficulty. Begin a new game on Insane and stick near Dom when the flashback starts, though you may need to walk away from him for a bit to get him to move at first. You'll know you're doing it right when he says "Yo" but you still need to stay near Dom for the whole flashback. It's okay to fight the Locust though, just be sure you're near Dom while you do it. When the flashback ends, if you did it right, everyone will have Dom's beard on them for the rest of the game. |
| Giant Golden Chicken |
| On "Chapter 1 - Act " you will reach four giant tubes just after raising the landing pad on top deck. After you eliminate all the enemies around the area, whatever player is playing as Marcus will need to step in front of one of the pipe openings. Stare down the opening until Marcus says "hello", then repeat the same thing for the last three tubes. After saying "hello" down all four tubes, a small, harmless chicken will pop out. If you deal some significant damage to the little chicken, the chicken will then become a giant, golden, enraged, fire-breathing chicken (a.k.a. Lambent Chicken). If you deal more significant damage to the Lambent Chicken, it will then blow up into confetti and ending with a funny quote by Marcus. |
