Slight correction:

Please be advised that online multiplayer services will be discontinued from 11 July 2023.
As such Lemnis Gate will be unavailable for purchase from 11 April 2023

Also:

Console players will still be able to access local multiplayer and training modes, however PC players will be unable to play beyond [11 July].

Not sure why that's the case (there's no clear technical cause for it), but it does seem as though the game will indeed become unplayable.

Thank you for the chance <3

Thanks Redpoison11! Hopefully I can give the game some love between now and the servers being discontinued
