The goose and duck roles, also known as the good camp, have different abilities and need to complete the condition of voting out all the bad guys or completing tasks to win. To achieve this goal, it is very crucial to clearly understand their abilities and usage, and to distinguish between friend and foe. Therefore, this article will introduce the goose roles one by one, to help everyone directly understand how to win.

1. Gravy Goose
Gravy can increase their bounty by completing tasks. Players with killing ability can only kill us when alone with them. The bounty can only be obtained if they survive until the end. When playing this role, it's important to team up with confirmed good players, and finally choose a trio to increase your chances of survival.
2. Medium Goose
When using the skill, the Medium can know the number of ghosts, thus inferring how many birds are still alive. This is an information-gathering role that can help identify suspects on the field and assist the geese in winning. Justices and Sheriffs, who have the ability to eliminate, will be our good helpers. It's best to find these two identities as soon as possible in a game.

3. Justice Goose
The Justice has the ability to eliminate any bird once. However, this single use might be the key to deciding the victory, so it's recommended to save it for later. You can work with the Sheriff to find teammates with important information and help them make the move.
4. Sheriff Goose
The Sheriff can eliminate any player without a limit on the number of times, but eliminating a good player will result in both dying. Only eliminating neutral or bad players will not cause trouble. It's suggested to play this role alongside Justice, finding suspicious players and letting them help test the waters.

5. Canadian Goose
His ability is that if he is killed, the killer will automatically call for a meeting. When playing this role, you can first tell 2-3 people about your identity, then go solo to do tasks. There's no need to stick together; the goal is to sacrifice yourself to help teammates identify the bad players.
6. Engineer Goose
The Engineer can hide in boxes, cabinets, etc., to ensure his safety and can move through ventilation ducts. During the period when tasks are being sabotaged, everyone can see the general location of the destructive ducks on the mini-map.
7. Mimic Goose
Mimic can make the bad guys think we are one of them, so there's no worry about being eliminated, as long as the true identity is not revealed. Since we have no abilities, we can only prompt suspicious individuals to act, helping the team confirm who the bad guys are.

8. Detective Goose
The Detective can investigate whether a player has a killing record in the current round. If they have, they will appear as a demon; if not, they will appear as a white goose. This ability can determine the identity of the other party and provide critical information to geese with elimination ability.
9. Birdwatcher Goose
The Birdwatcher can see through walls to the other side, but the view is limited to a flashlight perspective. The skill cannot be used during blackout sabotage. When playing this role, note that you are an observer. When a suspect appears, you can hide in a suitable position to watch their actions, or check if anyone is around the wolf's task points.

10. Bodyguard Goose
The Bodyguard will receive a reward after successfully protecting a designated role. If you are near the protected person and the bad guy attempts to eliminate the protected, you will step in to block the attack and sacrifice yourself.
11. Politician Goose
The Politician can survive in a tie vote, meaning they cannot be sent to jail. Playing this role, you can use this characteristic to prove your identity to others.

12. Locksmith Goose
The Locksmith can open the prison door at any time. When there is evidence that a good player is in jail, you can use this skill to rescue them.
13. Mortician Goose
The Mortician's skill is to investigate corpses, allowing them to see the roles directly. When playing this role, inform everyone not to immediately report when a corpse appears, wait for you to check the identity, and do not reveal this identity to everyone. Use the information from the deceased to question the identities of others and determine the suspects.

This concludes the introduction of the goose and duck roles. By familiarizing yourself with their corresponding skills, you can better speculate and judge in the game, uncover the infiltrators, and enjoy the fun of this multiplayer social deduction game, ultimately achieving victory.
