Buried in Time Easter Egg - Caldoria* Explosion

At the Main Menu of Buried in Time, press and hold Ctrl on the PC, or Option on the Mac, and while holding the key, click "NEW GAME". I think you have to have "PLAY INTRO" selected. Instead of the normal intro, a clip of Caldoria exploding will play, after which you will be taken back to the Main Menu.

Note: the timing of the key pressing is the same for the Moonwalking Agent egg.

(*This is the name of the place that is exploding in this egg. It is spelled correctly.)
