This summer saw the release of Assassin's Creed Black Flag Resynced, and players are gradually exploring the remake's content. As it turns out, the developers hid a secret shanty called "Home Across The Sea" in the game.
To obtain it, you need to activate a secret dialogue. The main character, Edward Kenway, must go to Nassau at coordinates (597, 767). A drunkard should be standing near the armory, singing.
For the dialogue to appear, you need to listen to his song for about half a minute, after which a dialogue activation button will appear. Then a few short phrases will be heard: the NPC will give Edward a shanty that players can select on the ship.
A user under the nickname MutantLeagueMVP also noticed that Assassin's Creed Black Flag Resynced has another Easter egg. He looked closely at the song's drawing and noticed that it was a subtle reference to a "rickroll".
He explained that people who can read sheet music would understand it: in the in-game "Animus" database, for all shanties, the developers used images with a fragment of the sheet music from the famous song "Never Gonna Give You Up".
