I regret to inform you that Decay mod is no more, there were many issues that we tried our best to solve them but unfortunately we couldn't, it was just inevitable that this project will fail sooner or later and we just had to stop.
But its not over, we are trying to pick things up, form a new team, find a new engine, hopefully Decay will still live on but as a stand alone game, we are still not sure yet, I do hope that one day Decay will become a reality.
I thank everyone who helped us and if there is anyone out there waiting for this mod I apologies to them.
Thank you all and goodbye.
**** luck, man. :/
But IF you decide to continue it some day, i warmly recommend the source-engine.
I still wish best of luck for your future(?) projects.
