Crytek will never "replace" Hunt Showdown with Hunt 2 the way Overwatch 2 did Overwatch 1
Crytek have no plans to make a sequel to sweaty monster-culling FPS Hunt: Showdown, and will thus hopefully avoid the publicity problems currently faced by Activision-Blizzard's Overwatch 2 and Valve's Counter-Strike 2 - both presented as sequels with fancier technology, but in practice, more like service-game content seasons arbitrarily upgraded into replacements, with the 'previous' games, Overwatch and Counter-Strike: Global Offensive, being taken offline to avoid splitting the playerbase.
Speaking to me in an interview about Hunt's evolution since its launch out of early access in 2019, the game's general manager David Fifield observed that while Crytek may yet make another Hunt game it won't be a straight Showdown follow-up - and it certainly won't come at the expense of your ability to play the original game.
