Not entirely. I have not totally given up on the project but it is parked for the foreseeable future.
I have not had the time personally to work on it and there has been little support from anyone else. May get around to doing something when X4: Foundations gets released (will look at making it compatible with both games).

is this dead?

@3Dguy: not so sure about that, the general idea is/was not to make an X4 but just to add to the X-Rebirth experience. I have been busy with other things since the inception of this mod collection and have not had as much time to pull things together as I would have liked.

This. This will save this game, just like X3: Reunion X-tended gave birth to X3: terran conflict. Egosoft made a huge, broken mess of a game with Rebirth so XXR is our final hope to get the real X4 in our hands. If some ideas can be implemented, this game will turn more awesome than anything we ever played in our lifes, and i´m not exaggerating. Great initiative guys, well done!!!

I would love to see more systems added by the community so far the community has made 4 systems but There is plenty of room for many many more. When i have time im going to start looking into making systems.

you need to help modelers and textures?

good luck on the mod you guys! Its great to see somde modders actually trying to add ship/station models to the game rather than fixing bugs

Thanks!!!
