Cayo Perico finale linux

I have set up a cayo perico finale years ago with max gold bars in all keycard rooms i think its 6?
I waited for my friend to help me but eventually ended up not playing for a while. It would be a waste to solo complete this and not get gold, so need a second person to help me with it. I am on linux though, (the dns trick) so no public lobbies and not sure if whoever wants to join needs to do the same as we on linux or what. I remember a bit about the stealthy escape left to the water but am a bit rusty. Lvl 125.
