This looks badass, but unfortunately nowhere near completion.
Still worth linking though simply because Arx Fatalis needs & deserves much more attention than it gets.
A prequal on Doom 3 engine was a bit of an odd choice. Sure, works for The Dark Mod because Thief is alot older than Arx and doesn't have as complex gameplay, for this TC these guys have coded all the RPG systems etc from scratch, plus IDTech4 aint much newer than the engine that Arx uses (whatever that is).
In that demonstration vid the gritty atmosphere and visuals so prominent in Arx is really lacking, though it is still an alpha build.
Still, an unnoficial prequal to Arx on DooM 3 engine will be much appreciated because I doubt we will be seeing an official Arx sequal/prequal anytime soon.
Glad they got dooms sprinting in it too.
If there is one thing they have to do though it's use some of Arx's music and SFX, which were brilliant, some of the locations in that demonstration were the same as the game, they definately should use the music from arx in those areas. Doesn't look like Arkane have allowed them to use the assets though unfortunately.
I really like the english voice acting too in Arx, an excellent mix of good and downright terrible just like Deus Ex.
