A supplemental set of Night Fighter rules for WW2 air combat. Beneath a Moonlit Sky is a supplemental system for use with hex based table top air combat games. To date, the game has been tested with Knight's Cross and Above the Clouds. But it should work equally as well with Check Six, Hunters in the Sky, or any other hex based system. The rules hereafter describe hidden movement and radar tracking using early Ground Control Intercept and Air Intercept radar systems. With just enough uncertainty added to give the feel of fighting in the dark, hunters and intruders make their way through the night sky, tracking incoming bombers intent on hitting their targets. —description from the publisher
