Does anyone know what the secret achievements in Monkey Island: SE are, and how to get them? (I love Monkey Island, and was somewhat shocked to just now look at my achievements and see that not only are there four I didn't get -- but that they're secret, so I don't know how to get them!)
All achievements are Secret Achievements in The Secret of Monkey Island: Special Edition, so here is the list of all Achievements and their descriptions. (source)
The Three Trials
Completed Part One: The Three Trials. Guybrush proved himself worthy to be a pirate.
Complete Part Two: The Journey. Guybrush used a voodoo spell to travel to Monkey Island™
Under Monkey Island
Completed Part Three: Under Monkey Island. Guybrush traveled into the Monkey Head and got the root.
Guybrush Kicks Butt
Completed Last Part: Guybrush Kicks Butt. Guybrush stopped LeChuck from marrying Elaine Marley.
Guybrush learned all of the insults, and is the wittiest/deadliest pirate what ever swung a sword.
Ten Minutes Later...
Guybrush can hold his breath for 10 minutes, but not any longer than that.
Escaped from the monkey island cannibals hut 5 times.
Collected all of the notes and memos sent between Herman Toothrot, LeChuck and the Cannibals.
Finished the entire game in record time. We hope you were wearing a helmet!
Experienced the original, classic adventure game, as it was in the early 90s.
Completed the game without using any hints.
Re-marooned Herman Toothrot and marooned Carla, Otis and Meathook on Monkey Island™.
I think "Marooned Everyone" requires you to play through twice, once sinking the boat with the rock shooter, and once without.
