Coils within coils—there is an impenetrable mystery at large connecting a series of ostensibly unrelated indie games. The Reddit hivemind (opens in new tab) is currently at work cracking the meaning of the strange sigil that has been added to various games since as far back as 2014 but is only now coming to light, accompanied by map-like puzzle fragments.
After the discoveries appeared separately on assorted subreddits, user MachMatic (opens in new tab) made the connection. In The Magic Circle (opens in new tab), the sigil appears on an airlock (opens in new tab). Dying and leaving the airlock with some clever platforming reveals a puzzle fragment (opens in new tab) in all its neon glory. In May, eye.jpg (opens in new tab) was added to Crypt of the Necrodancer (opens in new tab), and having a crack at it with a hex editor (opens in new tab) reveals another puzzle piece (opens in new tab). A hidden map, Canberra, accessed through an eye concealed in the credits, was added to MiniMetro in February. As discovered by nint8835, arranging your stations correctly (or cheating) unlocks one more chunk (opens in new tab) of puzzle.
Non-Steam browser game Kingdom of Loathing also features the eye (opens in new tab), a relic of an October 2014 update, as does the beta build of Legend of Dungeon (opens in new tab), from which good old-fashioned datamining extracted yet another map fragment (opens in new tab). There the investigation has stalled. How many more fragments could there be? What connects the games, and where on Earth or elsewhere could this be leading?
If you'd like to lend your expertise to the hunt, there are a number of discussion hubs accessible through MachMatic's original post (opens in new tab). The meat of the investigation looks to be taking place on the /r/gamedetectives' Discord channel (opens in new tab).
