UT99 and all the Unreal games have been delisted from stores and they're shutting down the game's master server. You can still play solo or in LAN but online multiplayer is gone and there's no (legal) way to get new copies.
as someone who has played so much of these two games: both are incredible games, in their own way - creating/testing maps, the weapons, the movements, the game-modes, the moddability (skins, sounds, etc)...so good
