Here's BO6 safehouse secret piano code

[W✩]

Whenever you get a chance to roam around the safehouse, find the piano. Use the uv light so you can see labels for each keys, they're in russian btw. Play the keys in sequence Mn-Pe -Cn-Ao-Pe or 5 4 2 3 4 if you're on pc. You'll unlock a secret door beside the piano and you'll get a free bill clinton operator for multiplayer. Thank me later
