The new version adds many changes to both players and AI as well as some bugfixes.
This release was mainly focused on Orks and Chaos (as the previous one was in Necrons and Tau) but contains campaign innovations for all factions, including a recolor of all factions in the campaign.
Should give a link somewhere in the post...
Sorry, I am somewhat unfamiliar as to how news appear. I thought it would appear within my mod page as clicked, and as such links would be unneeded as people could see the download section at any time.
The link to download the second alpha is here:
