After your first play through the game will give you New Game+ and at this point if you want to grind out the endings it is recommended to do this in Easy mode because you don’t have to reload and each level is only 1 wave instead of 3 and drastically speeds up the process.
1. Canon Ending
Shoot the dog during any duck round (Sound will confirm) and then make it to the “Come at me level”. After that defeat the Dog by keeping the TV Safe. When back in the living room pick up the game gun on the ground and kill the dog when he shows up. (about 5 shots)
2. Die Ending
Do the same thing as “Canon Ending” but let the dog kill you in the living room.
3. Stuck Ending
Same process as “Canon” and “Die” but let the dog break the TV in the “Come at me” level.
4. Best Men Ending
During the News Report or the level after there will be a phone on the ground. Pick the phone up and a 911 call will be made. Listen to her she will say “keep doing what you are doing help is on the way” and then finish the game and just watch the ending. (unsure if you must shoot the dog before this happens but shooing the dog will work.)
On any play through except the first one you will start seeing random golden bullets sometimes at early as level 1 but i am unsure what causes the golden bullets to show up. you can see them in the Ammo boxes on the truck. one shell in the left box will be golden. empty your shotgun and spam the shells until you get the golden one and load it in and shoot the Sun.
6. Fiesta Ending
Go through a play through and do not shoot the dog at any time. This will trigger the Bed time hindrance and you must go to sleep. You wake up and play the Fiesta game and the game ends.
7. Dog Ending
This must be completed after you have the other 6 endings. Do the Fiesta ending again but this time you will see a different cardboard cutout during the bedtime sequence and he will be looking at a VHS tape. When you load back into the livingroom the fiesta game will be on the floor but also this time there will be a VHS tape that reads “its me” on the side. Play this for the final ending. It is worth noting that anytime you put this tape in the VCR it will trigger this ending even if you were not planning on it.
