The attached zip file contains two versions of a new "hybrid" coop mission for RoF. The missions are identical, except for the weather.... which makes them seem like different missions

"LT VERDUN HYBRID FAIR WEATHER": 07:00, partly cloudy.
LT LT VERDUN HYBRID FOUL WEATHER": 07:00, heavy overcast and light rain.
This mission allows respawn and join-on-the-fly because it is actually based on a "Team Deathmatch" format.
Inside the zipped file, you'll find 8 files. Remove them.
The files go here: E:\Program Files (x86)\777\Rise of Flight\data\Multiplayer\DogfightHuman players can fly cooperatively, or on opposite sides. Air and ground spawn points and a variety of planes are available. There are enough AI bandits spawning in that it creates a heavy-battle, campaign-type experience.
Let me know if any "issues" occur.
Best wishes.
