Scenarios are aircraft only missions with the planning stage that can be run and rerun until you figure out how to defeat them.
Currently there is only one scenario available, but more will be added in version 1.17b22.
Available from the mission menu, the scenario starts by showing the small map the scenario will take place in, along with showing enemies’ locations and ranges.
The player places aircraft on the map outside of designated no-placement zones. This avoid the player being able to place units in direct proximity to enemies and instead makes the approach important. There is generally a low supply count, so only a few units can be placed.
When the player has chosen their units, placed them and given them equipment and orders, pressing start will immediately start the scenario. Whenever the player wants they can restart and chage their planning until they win.
