1. More than 90% of the sounds have been re-sounded. Many of the voiceover sounds, with the exception of some minor ones, have been replaced with new ones.
2. Most of the voiceover sounds have switched to "walkie-talkie" sounds, so now you can adjust the volume of the voiceover of radio conversations separately from the sounds of "music" and "effects".
3. New soundtrack.
4. A new event with a power outage throughout the base in 10 missions.
5. Cutscene changes. The protracted moments have been shortened, some angles have changed.
6. Script changes for a more correct game.
7. Changes to some briefings.
8. Customization changes for some locations. In particular, the hospital of the 12 mission acquired an interior inside on each floor; the airfield of the 13 mission received several barricades and shelters.
9. A large number of new markers on the map in each mission.
10. An epic trailer on the campaign page in the workshop ;)
