Total Chaos 
Any deets on the final release?
Hopefully next month. Stay tuned!
Im new to this and omg it lookes amazing.. but when you say final release is that just for this expantion? or is it a final release as a whole project? the base game and the expansion?
The game without the directors cut content has a final release, can be found here:

Final release containing all of the Directors Cut content is still on its way.
Loving the game, just found it a few days ago. Should I wait for the final release or play through the beta?
It’s been more than five years since you published this mod, that’s some serious dedications.
Keep up the good work!
