Project Z originally launched in 2016. And though it was short lived, (no pun intended) there's nothing like a cult following for a zombie property. As such, Warlord Games is going to be running a very limited-edition pre-order run of the game with updated rules over on their website.
From the website:
Back by popular demand! Keen gamers may recall that Project Z originally launched in 2016. Although the game mechanically remains unchanged, the rules have been updated for clarity and consistency. This re-release has an extremely limited print-run, and will not be made available again when sold out.
