I have the Survival distro, as it seems like the best way to get the Day-Z vibe. I just have not had any time to work with it

It is a shame but in this day and age, if there are no epic youtube vids, any project way as well not exist.
There will always be the question of "what is the point ?" with projects like this, but what is the point of Oldskool Ampd, or the Botpack conversions, or the original UEd1 only project ?
Gizzy was also doing the 2k4 weapons for Unreal until he left the scene.
Like every one that ever climbed a mountain, these projects are simply "Because it is there".
Personally I would have thought that NW3 would be a better framework to develop on, to back-port fancier weapons from a fancier engine.
I agree with Jack's sentiment though, in that, if the weapons are exact, well we sort of don't gain a lot from what we already have.
However, I have a suggestion that may make everyone happy.
Once you have perfected them, perhaps you should port the 2k4 Chaos weapons.
These babies would go down a treat, as the napalm grenades look a treat, and cause absolute chaos as intended.
The 2 remaining members of the Chaos team, are very friendly and may be able to give you any resources.
