New special effects have been implemented. Aircraft will now attack as a team against a single enemy aircraft. No longer will a flight of multiple aircraft attack an enemy aircraft one aircraft at a time. This option allows much greater frame rates while using the mission editor and other menu screens. Players can now land on roads.
Missions now start in a new paused mode.
This removes the stuttering seen at the beginning of mission of previous versions of Flanker 2.0. Flight model enhancements for both player-flyable and AI controlled aircraft are present. Additional wingman communication options have been included. If you are an owner of a Voodoo graphics card and you would like higher resolution graphics, you have the option to download versions of the upgrade specific to Voodoo cards. To upgrade to Flanker 2.5, you must install Flanker 2.5 over a clean version of Flanker 2.0.
