Now let's see this working for Darkest Hours. ;)
(Assuming they didn't fix it themselves, it is a pretty big overhaul to MC1)
99% sure it should work fine for (Exodus and Turncoat), (X-Ray and DSC Raid), and (Xenocide and Bengal Lancers) since those are just custom campaigns.
Lovely stuff. Always a joy to see anything MechWarrior related end up here on HN.
