Since most of the early birds who ordered The Journeyman Project 3 for Mac OS X should be receiving their DVDs by about now, we can share how a bunch of us on the dev team squandered the precious free time of our youth. By holding down the tilde key (near the top-left corner of your keyboard with the funny squiggle, usually located right below the escape key) on Macs, or the "e" key on Windows, you can unlock one of at least 17 once-known easter eggs in the game. By "once-known", that means we had once kept good track of them so that we could let the QA department know about it in case any of them might trigger an unexpected bug. However, it's been over ten years, so we'll dig up hints for these as best as we can for your gameplay pleasure.
This first one is fairly well-known: hold down the "easter egg" key (noted above) while clicking on Agent 3's empty JumpSuit when it first appears in the destroyed Atlantis environment. The result is a warning against leaving potentially embarrassing Halloween pics lying around imaginative co-workers.
