I’ve put together a new Windows build that should be pretty close to what I have in mind for Alpha 3. It adds a ton of new features, fixes one serious bug (armoured trucks!) and a number of minor ones, and adds a new campaign and a new nation to play. Download here
Update: I just uploaded a hotfix that fixes a typo in the code for resolving FP attacks on unarmoured vehicles that would cause a crash. Old saves are still compatible.
