I used to play Tremulous years ago, and it was a great game (although I could never get the hang of the aliens that could walk on ceilings). As the author says, Unvanquished looks amazing but when I last looked at it (over a year ago), there are just no players. It's a real shame; both these games were/are probably just as good as the latest crop of "professional" FPS games like Overwatch, but just haven't achieved a critical mass of players.

Regarding Unvanquished I have to disagree... yes it looks great relatively speaking, but it plays (and mostly sounds) just like 15 year old Tremulous. I don't want to belittle the amazing work they have done so far, but IMHO the gameplay is what is holding it back.

Wow, I'm surprised there are actually 10 FLOSS FPSes out there. Although Sauerbraten was non-free assets.

Sauerbraten is kosher now, as is that sweet fork Red Eclipse.

AFAIK nothing has changed about the non-free asset license of Sauerbraten. Red Eclipse is Free Software though if you can overlook some issues with how they run their master-server.

I can apt install Sauerbraten, so IDK what's up there. Maybe I've got the non-free repositories enabled. I know Wouter had only the best intentions, and anyways if it's just NC it's nbd imho. If you want libre engine+assets there's BananaBread.

Is Blasphemer an open source Heretic version or Hexen? Looks like it is Heretic. I didn't like Heretic but liked Hexen.

The Heretic engine is just the Doom/Doom2 engine with sloped floors, so Blasphemer is Heretic. I don't really mind Heretic, but I always wanted it to be closer to Dungeon Master or The Elder Scrolls.

FWIW, I recently wrote an open-source multiplayer FPS engine, humbly called SteveTech1: https://bitbucket.org/SteveSmith16384/stetech1/

I created a few games with it, one being "Two weeks in the pub" (a pun on the names PUBG and Fornite that this aimed to clone):-
https://bitbucket.org/SteveSmith16384/twoweeksinthepub/

And one called Moonbase Assault:-

Awesome! I'm not too comfy with BitBucket; what's the Git URL to clone it?

For the engine itself, it would be "git clone https://SteveSmith16384@bitbucket.org/S ... etech1.git"
For Two Weeks in the Pub, it's git clone https://SteveSmith16384@bitbucket.org/S ... thepub.git
Moonbase Assault is "git clone https://SteveSmith16384@bitbucket.org/S ... ssault.git"

Let me know if you have any questions/issues.

The engine download is over 200 MB. Would it be possible for you to remove all the assets and jars and force push? It's a terrible practice to put binary dependencies in a source tree, and the download size just adds insult to injury.

They have it in the non-free section just as before.

I've no idea why Bitbucket is reporting the engine download to be 221Mb. I've just downloaded it myself and it's only a 23Mb zip, which unzips to about 63Mb.

Edit: I had a quick google, and it's a known issue with Git/Bitbucket's garbage collector.

OK, yeah, that's a Git thing. That's why you force push.

Even so, don't package binary dependencies with source code ever.

Why not? It solves all the dependencies hassle. I wouldn't include massive dependencies, but ~4Mb of included jars is a small price to pay for just getting the software to compile and run.

Genuine question: What security audit?

How does that apply to this multiplayer FPS code? Are you looking to use it for Air Force training?

Unreal Engine has been applied to the same purposes.

Just to be clear, this is just for the purpose of illustration. It's not important that your engine be used for that. UE does license their engine code, but from what I hear it's massive and probably costs a lot of time to inspect, not that anybody in the military even cares about software security. My own standards are rather high.

Fair enough, but I think I'll keep the project the way it is.

I thought I'd just give Tremulous another go for the first time in about 10 years. Loads of servers, all with a grand total of 1 other player, who seemed to play some kind of invincible alien.
