Very interesting find, I had no clue the studio was bought out in 2020. With the case study that Phoenix Games has listed on their website as well as what you quoted from the case study, it looks to me that the beloved series that we know of is most likely dead. I feel this might be more of the case because when doing additional research on Phoenix and the game studios they currently own it seems that all of the studios owned are primarily producing free-to-play titles that are exclusive to IOS and Android devices. There was only one game made from sister studio Wellplayed Games that has a game that is for Xbox, PS4, Switch, PC . besides this title the only other game(s) that Phoenix has under all of their game studios is 16T with all of the Emergency titles that are available on either Steam or the Mac App Store. Thus after doing this research it makes me believe that in my opinion that they seem more primarily focused as an organization with creating games for mobile devices. Phoenix Also states on their website that,
This just added more fuel to the fire that building games that have the features that the community want will be outweighed by the leaders and administration at Phoenix Games to please their investors. I don't like to have such a negative outlook on everything but it seems more likley than not the "Classic Series" of Emergency might be dead in the water.
