Easter eggs

There are several Easter eggs in Obduction, and they are divided into two categories: (1) traditional Easter eggs, which are objects in the game that reference past Cyan projects, and (2) Easter egg codes, which can be used to view images on the slide projector in Farley's Community Center. Several of the latter were placed in the game for Kickstarter Backers in the "Egg-sibitionist" tier.

Traditional Easter Eggs

 * Locomotive valve
 * Myst Book
 * Manhole advertisement
 * Moula Cola
 * "Who the devil are you?"

Easter Egg Codes
'NOTE: There was a bug in version 1.5.2 of Obduction'' that prevented it from accepting Easter egg codes. Please update to at least version 1.6.0 before following the instructions in this section.'''

To use these codes, you must first break the Box of Infinite Complexity. Enter the Box of Infinite Complexity code into it while it is up in the air, and it will fall to the ground. Then enter the code 0118-9998-8199-9119-7253. (This is a reference to a comical commercial featured on The IT Crowd, a British sitcom.) If it is entered correctly, the lights on the box will begin to blink randomly. Then you may enter any one of the following codes, which, if entered correctly, will cause the lights on the box to turn green for a moment. You may view the image associated with each code by visiting the slide projector in Farley's Community Center. Doing this for the first time will grant the Eggcellent! achievement.

(It is recommended that you switch to point-and-click movement to minimize errors whenever interacting with the Russian light box.)
