The main victory conditions for the good guy roles in the mobile game Goose Goose Duck are to complete tasks or defeat all the bad guys. For this, they have a variety of different abilities, but this also leaves many new players confused when using good guy roles. The following introduction to the good guy roles will take you through their abilities one by one, so that new players can better utilize these abilities after understanding them.

1. Gravy
Gravy's ability is that he cannot be assassinated by the Assassin, but there's a restriction: he cannot be alone with a Wolf, nor can he be too far away from others. If either of these situations occurs, he will still be killed. Therefore, choosing him allows you to directly announce your identity at the beginning and choose someone you believe to be a good guy to stick together with. Additionally, after completing 1 task, Gravy will increase the bounty at the end of the game.

2. Medium
As the name suggests, the Medium can see the ghosts of dead geese. Using the skill will display the number of living or dead players on the field. So, if everyone sees no one has died in the last second, and then an alarm suddenly goes off, you can use this to determine whether the Canadian Goose has been stabbed, helping to find the wolf.
3. Canadian Goose
This is a rather special role. When killed or swallowed, it triggers an alarm. At the start, you can choose two people you trust, reveal your identity, and do tasks. Since the murderer who kills you will automatically trigger an alarm one second later, you can use this to find the wolf.

4. Detective
The Detective has one chance per game to check if a player has killed someone. If they have, a small devil will appear in front of their name; if not, a small angel will appear. Note that if the player kills someone after we use our ability, the angel icon above their head will not change to a devil, so use it carefully. If you successfully identify a killer, you can immediately call a meeting and vote them out.
5. Bird Watcher
The Bird Watcher's ability is to see outside through walls, which is very useful when closing doors. If you can see useful information, you can directly catch the wolf.

6. Influencer
When the Influencer is killed, all good geese will receive a notification, but unlike an alarm, neutral roles and wolves cannot see it. You can use this information to question suspicious people during meetings, such as asking "In which round did the Influencer die?" to conduct investigations.
7. Mortician
He can investigate corpses and check what role the dead person was. As long as he finds a corpse, he can use his skill on it. After the investigation, the role of the deceased will be visible during the meeting.
8. Engineer
This role is also very useful. When bad guys are causing trouble, there will be a red circle on his map indicating their location. Additionally, he has the ability to use vents and pipes, allowing him to hide and quickly escape in times of crisis.
9. Lovers
The Lovers could both be good geese, or one goose and one duck. When you select the Lover goose, you need to find the other Lover. Both Lovers will see each other's names in purple. Once found, you can privately communicate your identities and try to stick together for tasks. If we are a goose and the other is a duck (or a wolf), we need to make sure our Lover duck does not tell their wolf teammates about us, as if one Lover is killed, the other will also die. Lovers surviving until the end will have a separate win condition.

10. Vigilante
This role starts with a knife, which can be used to kill anyone, whether good, neutral, or wolf, without any consequences. However, as a good guy, we need to be cautious to avoid accidentally hurting our good teammates.
11. Sheriff
The Sheriff can continuously stab, and if the target is a wolf or a neutral, they won't die, but if the target is a good guy, the Sheriff will die immediately. If the Sheriff stabs the special Canadian Goose, both will die, but without triggering an alarm.
12. Politician
The Politician can survive in a tie vote, meaning they can prove their identity by showing that they cannot be imprisoned.

The above is an introduction to the good guy roles in the mobile game Goose Goose Duck. Understanding their respective abilities should help you play more confidently. However, since some good guys can also kill, everyone must be cautious and carefully judge the situation to achieve victory.
