etlegacy VS OpenTESArena

You could try Dirty Bomb or the classic Wolfenstein: Enemy Territory for some class-based objective shooters. Both are free to play.

ET Legacy Wolfenstein Enemy Territory, FOSS client. Maybe moot since an official client re-released on Steam recently.

It doesn't replace any server, it's a new one on Legacy mod - https://www.etlegacy.com/

Look up ETLegacy some nice guys from the old scene have basically remastered it - hd graphics updated sounds etc. All things in one place!

ET: Legacy

Have you tried using ET Legacy? www.etlegacy.com It's basically the same ET client, but updated to current standards.

As you pointed you need source code that can be found here: https://github.com/etlegacy/etlegacy

Off topic, but if it was Wolfenstein ET I will just add that there still is a community for it and a Foss version of it that runs on modern operating systems

Arena: Waiting on a playable release of OpenTESArena.

Here's the Arena remake project, which is not using Unity but is instead a complete reimplementation using C++: https://github.com/afritz1/OpenTESArena

Here’s a good source to read first. It’ll help you set up your first character so you don’t waste much time failing again and again. I also want to jump into Arena but I’ll wait for a wholesome OpenTESArena. The controls are of the previous century making it very tiresome to play. You could also see some playthroughs on YouTube. Imo it’s worth some time to play around a bit in Arena but if you plan to move on to Daggerfall, go straight to DaggerfallUnity. Cheers and have fun. (And say goodbye to friends…)

Your options are going to be very limited, especially since OpenTESArena has not even reached Beta state yet. But TES Arena Remapped let's you play with WASD controls (you'll want to rename the mapper file to your version of DOSBox).

Nonsense. It's definitely not. The last commit is from June 2022 (https://github.com/afritz1/OpenTESArena) and the Discord Channel active with the dev itself posting quite frequently.

I reckon that'll happen a few days after OpenTESArena gets mod support.

There is no such mod as of yet, but OpenTESArena is being developped and it might provide new options modders.

The Elder Scrolls: Arena has an experimental Linux client with no actual gameplay yet. The version on Steam is apparently the floppy version and is lacking some features, however it does run fine through Doxbox.

There is one, written in c++ https://github.com/afritz1/OpenTESArena
