Anyways so recently, there is a rumor going around that Charlie's sister Winona may be added into the game as a playable character. People have been claiming they even found numerous, numerous dialogue strings for her in the code; which have just recently disappeared. The dialogue actively referenced themes such as Winona being familiar with the factory workplace and mechanics, Maxy which was Charlie's nickname for Maxwell - Waxwell - William and that there is a potential feature which gives Winona one free hit from Charlie in the darkness.
Highly unlikely this is a prank from the developers for April Fools seeing as that would just be an incredibly poor way to infuriate the fanbase, Perhaps this may even be a prank made by fans themselves who are all falsely claiming that something existed in the code which isn't. But would like to believe people do not suck that much.
There is a mod for Winona, but it is apparently very outdated and the text strings found include dialogue for very modern updates to the game like the Atrium. So it could not be some player accidentally viewing a mod they installed as a part of the core game.
Would also like the believe if it was fake the developers would step in to disprove it all to save the playerbase a massive disappointment.
However the developers are also very well aware that any coding they put into the game is blatantly dug up as it is released, and that their fans are very much used to deciphering vague information the developers leave behind. Having Charlie's sister added to the game would also be a very logical way to advance the plot and hinting to it around April Fools just causes more chaos.
Any thoughts, information on the subject, so on.
