I'm still bitter that they unilaterally killed the entire Unreal Tournament franchise, pulled all games from all stores and turned off the master servers with no explanation.
I could understand maybe turning off the master servers to cut costs, but lets be honest, they could have hosted the entire franchise master servers on a raspberry pi. There was no need to pull the games from stores. They all but guaranteed there will never be any new players and the existing players all resort to piracy now when needing a new install.
At least give an explanation.
Unreal Tournament patches are still in development with official approval/support of Epic:
https://github.com/OldUnreal/UnrealTournamentPatches/
These patches include updates to the master server addresses which enable the game to continue working online.
Third-party master servers have also been available for at least a decade.
