404 Room

The 404 - Room

The 404 - Room is accessed via the Office after finishing the task for Hades' Assistant.

Inside, the player finds the "Chief Engineer". Talking to him opens up a window that contains all cheat codes for Neon Abyss. The player must unlock them by purchasing Cards at the Vending Machine. There are currently 199 cheat codes to unlock.

The cheat codes are accessed in a run by entering them in the games console, which can be opened by pressing the -key (can be rebound) on keyboard, or by holding down the pause button and map button on console (cannot be rebound). Using cheat codes will prevent any achievements from being unlocked during the run, as well as unlocking progress at the bar. (This will still happen if the cheat fails) Also to use a cheat code, the player currently must have acquired at least one faith gem during the run, as each code will cost one gem to activate. Also worth noting - even if you know the cheat codes, entering them in a run on a save file that hasnt unlocked the cheat code yet will result in the cheat not working.
