Exit 8 is the sequel.

According to the creator off the games hes not looking to continue this exit 8 series instead he will continue working on his horror adventure game strange shadows

He explained it here https://x.com/NOTOKEKE/status/1797055820552867876?t=KM0e992upRms_TK3O_HEJw&s=19

He made the exit series cuz off his love for the subway and hes satisfied with the 2 games on it so he has no plans to continue this number 8 series off games

Since there is already a sequel, it will be probably a pre-quel of the pre-quel where he it shows him the the departure zone, an air-port or something alike.
