Arx - End Of Sun is a new free and fan made game that is based on the first person dungeon RPG : Arx Fatalis developed by Arkane Studios.

In our game world you will play out the events ( with a liberal dose of poetic licence ) that precede the original story of Arx Fatalis.

The modification / total conversion itself is based on the IDTech4 (Doom3) engine.

You will no longer require a copy of Doom3 to play Arx - End Of Sun. We are now running on a custom version of the engine code and we use no assets from any commercial titles in our game.

Arx - End Of Sun is not an Arx Fatalis clone, Our game is full of new content based on the original game universe. We use no assets from the original game or any other commercial game. We are using a completely different and newer game engine. and we aim to capture a likeness and pay tribute to the original game of Arx Fatalis.

The Arx EOS total conversion is currently being developed by a very small team of hard working volunteers, everyone is working for free in our limited amounts of spare time, often sacrificing other activities or taking time off real work to work on our game. We hope that many people will enjoy playing our efforts when it is released.

The Arx End of Sun (Beta) is released!

A completely free and standalone game that is now available to download and play. Based on the game Arx Fatalis created by Arkane Studios. Note you do not need to have played the original game to enjoy Arx EOS although we recommend you do as it's a fantastic game!

Arx - End Of Sun - Beta Release

Arx EOS has an original storyline which loosely precedes the events of the original game. including RPG elements, problem solving puzzles, with faster paced melee and projectile weapons and a more forgiving magic casting system.

Arx - End Of Sun - Skeletons

Over 5 years in the making from initial idea to release, a lot of time, effort, blood, sweat and tears have gone into the making of this Doom3 total conversion. Created by a very small team of hardworking volunteers, everyone has worked for free in their limited amounts of spare time, often sacrificing other activities or taking time off real work to work on this game.

  • Nearly 2.5 thousand new textures.
  • About 1000 new models, static and animated.
  • All commercial assets removed and recreated / replaced.
  • A fully standalone game that bears almost no resemblance to its Doom 3 past life.
  • A long main quest spanning all 16 of the released levels.
  • A treasure hunt side quest.
  • Over 10 new monster types to fight against including: Goblins, Zombies, Poisonous Spiders, Rats, Demons, Snakes, Trolls, Cave Piranha, Reanimated Skeletons, Ylside Predecessors… There might even be a boss?

A unique feature to the Arx EOS id Tech 4 code enables the player to revisit the levels as many times as needed to complete the game. Items collected / dropped, quests completed and monsters dispatched retain their state across the levels each visit.

There are often several ways to complete sections of the game and you do not have to complete much of it in any particular order. You are quite free to explore the game world as you see fit.

The public beta has undergone several rounds of play testing and critical bug fixes before being released to the public and we have tested the game to be beatable from start to finish, however it is still possible that other issues remain, so please report game breaking issues to us so we can address them. We are currently not looking to address minor or superficial issues at this time.

I was watching this project for years (watched your blog, then sidebar activity), it breaks my heart that such promising project ends unfinished.

Good luck then, we gonna miss you.

I actually didn't even know it was released in any form. I followed the project back then, then I kinda forgot about it. And a Youtube video popped up and saw some gameplay. I'm shocked this exists. I loved the original Arx Fatalis, still one of my favourite RPGs, just for the atmosphere and uniqueness, it's closer to my heart than Skyrim.

I would love to see a true spiritual successor of Arx. And I'm definitely going to give this a try!

Check out " Monomyth " It is a spiritual successor to Arx currently in development.

Inspirational! It's crazy what you achieved with such a small team over the years, mad props to you guys!

Hello. Will you work on continue of game?

Reply Good karma Bad karma+3 votes

No nothing else is going to be done on this project. Making Doom 3 mods is hard work with very few people.

Arx End of Sun - it is a very good game, for "beta". Excellent work!
Good new story, nice music, nice dialogs, decorations, places/locations.

But there are several or more bugs, errors or mistakes in this game (blinking textures, stucking in the open/opening/closing door, hard to pass some locations because of bugs or technical errors; the main hero had to move slowly: it looks like a swimmer who is swimming upstream).

I think the game need another (one more) patch.

No more work is going to happen on this. We've all moved on.

Very sad to know that but as someone that is modding idtech 4 in my spare time as well, i sure comprehend why you guys decided to go away from it, is hard specially when working on the C++ code with almost no direction, but Will you guys release the source code so others can perhaps work on it, would be a shame and a waste if it would be lost in some HD somewhere.

Reply Good karma Bad karma+1 vote

Yeah it's up to solarsplace to upload the source. Although maybe it might be in the download? I haven't checked and I don't have it downloaded.

Excellent level design, cool missions, nice models and textures, nice puzzles. So far I'm having a blast. Good work pays off and this is a big payoff. RPG on idtech 4 works so well. I hope you guys continue to polish and add to this.
