This pack is a mix out of the original KA-50 campaign pack and MadDog-IC's awesome work on converting this campaign to DCS 2.5 incl. English voice over.
When flying the campaign I found that the original files where very buggy and not every mission could be completed (some entirely impossible due to unit placement, missing triggers etc). The result is working a mix out of original and MadDog-IC's work. Took a long time but at the end I was able to complete all missions as intended.
All credit goes to ED and MadDog-IC
