I'm writing this strategy guide here because it has more than 2000 characters, so I can't place it under the strategy guide section of the setup.
Day 1
Spy needs to contact sniper first thing and also spy needs to look out for presidents vote. If you get shot by the sniper because you voted the way the president would vote, you trolled your partner into killing you and will probably be a dumb enough into reporting them. If everyone votes someone, unvotes, and votes someone else, than there is a chance, depending on the speed it was done, that they were president.
Claiming gunsmith day 1 is completely unless you're getting lynched. If you're bomb, mafia, or gunsmith and you are getting lynched, claim gunsmith. If you are gunsmith, claiming is stupid because it doesn't matter if anyone kills the person claiming gunsmith or not so long as you aren't the one getting lynched; Second, mafia will just have a safe kill for the night so they don't have to risk hitting bomb. Really stupid to out as real gunsmith day 1 unless you are getting voted or trying to trick mafia. Don't counter claim gunsmith if you really are gunsmith or are bomb.
If you are president, just act like everyone else and ask people why they are voting the president when they are voting someone who isn't the president. If you are bomb, do the same thing. If you are gunsmith, do the same thing. Always troll by asking why every ones voting president or claim gunsmith as bomb before the day ends.
If you are sniper, don't take the shot unless you are being voted while no one believes your gunsmith claim or are absolutely sure someone is president. Your bullet will be important later, even if you get hip fired the next day.
Night 2
If you are spy, now would be the time to take a guess. If you don't take a guess, you will make it harder on your sniper buddy when they have a higher chance to hit bomb during the day when they have a gun and can't be lynched without retaliation. You can be lynched without being able to do anything about it like your partner, so you are expendable. Go for president.
If you are gunsmith, GUN THE PRESIDENT. If anyone tells you not to gun the president, tell them to go back to their skype circle jerk kabal. The president needs the gun to make the final decision. Most people will gun the bomb and risk gunning mafia. If spy doesn't kill because they are a coward, they could end up with a gun which will give them a huge advantage. Gunning president on the other hand is much more simple.
Day 2
Most likely spy died and bomb died with spy or gunsmith died because they were stupid enough to counter claim day 1. When this happens, sniper has a time to shine. President will have a huge chance to hit mafia here if gunsmith claims, but, if sniper still has the bullet and spy is still alive, its gg if president doesn't hipfire a 2/3 chance of hitting mafia, fast enough.
If you're bomb, don't claim gunsmith anymore unless you want gunsmith to get shot with their own gun. If you are gunsmith, claim out loud if sniper is all that is left. If you are president, do what bombs are doing. If this is lylo because spy didn't kill and you lynch the wrong person, spy still has a chance to vote wrong in night and sniper will likely hipfire and win when it's lylo. This normally only happens if gunsmith actually counter claimed day 1.
Final Lylo
Here is likely going to be a sniper, bomb, gunsmith, and president, but, sometimes can be no gunsmith. If there is a gunsmith, claim only if you gunned president and want them to have to quickly hip fire against the sniper who both have a 50% chance of killing each other no matter who shoots first.
If you are the bomb and nobody has a gun except sniper, vote the president and claim you are the president while saying good game. If you are sniper and stupid, you will shoot the bomb at this point and die. If you are sniper and aren't stupid, you know they aren't voting mafia and therefore have to assume they aren't president. You can try to turn this against them by claiming who the real president is and get the actual president to take your side. Don't shoot unless everyone is voting you as sniper.
If you are spy and sniper is out of the game, same tactic, except you don't get to shoot when everyone is voting you. This will only happen if sniper gets voted out day 1. Don't be a dumb .
