Unreal Tournament 1999 is also still playable online with the Unreal Tournament Community Patch installed (it also adds other improvements like support for modern resolutions), you just can't buy the game anymore so you'll have to find it.somewhere.(make sure you get GOTY Edition). Some other fun arena shooters you should check out are Xonotic and Cube 2: Sauerbraten, both of which are completely free.

How to get Upscaled Textures, HD Main Menu/HUD, and HQ Sounds: How to fix the Resolution, FOV, and FPS: Check out my guides on how to do both here (or you can find them by just going to the game's 'Guides' page):

Also if you want you can install some upscaled textures to make the game look a lot better. Since it is old though, if you are playing on a modern monitor you'll need to do some tweaking to fix the resolution (don't worry its easy to do).

If you like arena shooters, even a little bit, this is a must-play. It's so good people are still playing this game online over 20 years later and it actually has a pretty good sized playerbase at that.

One of, if not the best arena shooter of all time.
