Unzip this file into your Codemasters\OF Dragon Rising\data_win\missions\ folder. In the game it will appear as a playable single mission.
This is a better version of the mission I previously uploaded. Please feel free to offer feedback and to follow the "Homepage Link" to the right to vote for this mission (until Dec.13th).
Credits: Much thanks to several people on the Codemasters forums, but especially to TemplarGFX. This mission wouldn't even be close to what it is now without his help.
