I remember giving UT99 a go. My computer sucked so I I guess it contributed to my not so great latency. Liandri and Deck 16 were the most popular levels to play in. I was fond of Tempest though. I sucked at the game. I loved that shock gun where you shoot that blue thing, and then shoot the other blue thing with the same gun to make the explosion and kill nearby people.
That's the only FPS multiplayer I've ever played.
Just trying to remove that damn setup progress bar.
