Miss the classic shooter from Splash Damage and id Software? Wolfenstein: Enemy Territory has a modern open source version you can play with ET: Legacy and there's a new release available.
Thanks to the original source being released back in 2010, it lives on with the dedicated team behind ET: Legacy and it's easily the best way to play the game with many improvements over the original while remaining compatible with the latest version of the original release.
From the release announcement:
It was also overdue, but now it's finally time for ET: Legacy 2.77 'Capture the City!', our most comprehensive release to date. Yes, we have been saying that about the past releases as well, but only because it's true! Thanks to an actually growing ET: Legacy community and more active interest and involvement by players and server owners alike, the amount of feedback we have received since 2.76 was absolutely astonishing. Thank you for that!

It holds a truly special place in my heart, as I played the original to absolute death during the time of the original Xbox. It got me through some tough times and so it's pleasing to see it doing so well - now free and open source so everyone can get involved.
For the Linux version, you're going to want the 32bit build otherwise you're going to have issues joining servers as as it seems most servers still only provide 32bit mods. Hopefully they will eventually remove those servers from the list in the 64bit client.
Grab it from the ET: Legacy website.
