I have replaced the original v1.2 file with v1.21b. This includes a steam version of the mod.
Unfortunately I have not been able to test this mod on the steam version, as I don't have it, or know anyone that does. If someone could confirm it now works, that would be fantastic.
In further tweaks, the latest version (v1.21) now has slightly more chatty AI, slightly increased pistol damage and the sawn off shotgun now actually uses shotgun shells.
