Click the flash drive and remember the code, which is always 1-2-1-4.

Then during the "Government Supported Private Investigator" ending, click the keypad that appears after the Vacuum option and enter the code, 1-2-1-4.

Then during the "Rapidly Promoted Executive"/"Relentless Bounty Hunter" ending, Henry will enter a secret room during the chase with the Toppat Leader where he finds the legendary Biggol Sword.

Bound to the Earth
In Henry's fight with the Right Hand Man, choose the option "Yo-Yo" to start an Earthbound-style fight, then "Goods" to win.

The Last Fantasy/Last Reverie

Original version only
These achievements are only in the original version of the game.

Failpocalypse
Fail a total of 100 times. Since the game only has 60 unique fails, this requires the player to get some fails more than once on purpose.

It is not confirmed yet of why this one is removed in the Remaster.

Kredit 2 Team
Watch the credits of at least one of the four endings without skipping.

This was removed because you can't skip the credits in the Remaster.

Music Enthusiast
Click on a music link during the credits of one of the endings.

This was removed because the sound links are after the credits in the remaster.
