Remedy Entertainment loves to hide clues about future projects in its games - in Quantum Break, the letters "AWE" pop up frequently, and from Alan Wake, we got the cryptic message about the "town called Ordinary" in Balance Slays the Demon - likewise the reversed message in Take Control had hints for both the AWE Aerobatics mod ("The diamond will tell you where; 1, 19, 7, 1, 18, 4, 9, 19 / Landing on the polar star and rushing on to the red room, find the cord to take you to a secret rendezvous," referring to the clock puzzle) and, to the best of my understanding, a bit of Alan Wake 2 ("In their drunken fevered states, seeing double, profoundly; the pyramid in the stolen file becomes a spruce tree," referring to the double-triangle/tree symbol of the Cult of the Tree). Thus, it is possible that hints for a future game, perhaps Control 2, could be hidden within the game itself.
So far, I'm noticing two major themes that are as of yet unexplored in Control - the prominence of the Willow and Sterling AWEs in several areas and documents, as well as the name "Blessed," tied to several Altered Items and AWEs.
There seems to be a good case that the Willow and Sterling AWEs are linked - the phrase "hollow sphere of stonelike material" and a mention of vitrified soil appears in both the Willow manifest and the Sterling reports, and a dog missing from the Sterling site is listed on the Willow manifest. Based on this, we can assume that the two incidents are linked in some way - mention was made that the Sterling monolith seemed to have "hatched," so perhaps the stonelike spheres are vessels or shells of some sort, sent by the same being from an adjacent plane. If the same spheres have appeared twice, there is no discernible reason they could not appear a third time or more, possibly serving as the main paranatural component of a future Remedy game
Likewise, companies and individuals with the name "Blessed" seem to be consistently tied to Altered Items and their usage - the fondue set that caused chaos at the America Overnight station and the ActionMaxx Camera were both traced back to a studio called Blessed Pictures, a guru named Chester Blessed was tied to the Surfboard, and the company Blessed Repair and Service is linked to the Songmaster Jukebox. This "Blessed Organization" seems to be both incredibly ruthless and solidly at-odds with the FBC, leaving open the possibility that they might serve as the antagonists in a future Remedy project.
Has anybody else noticed any particular themes or loose plot threads you think might pop up in a later Remedy game?
