As of last weekend, our GBS Server is running two different 'missions' 24/7.
One rotating the set of 4 DF a/c oriented missions (90min rotation), the other running the 'Tankcrew Summer' mission, created/tuned by dd_Friar, with options to battle in open field and in towns, or to practice at a gun range. It will restart itself after 3 hours of running. Yeah, bad luck if/when you kill all possible targets on the map in the first half hour - you better go fly for two and a half hours. Note: Some targets will quickly re-spawn after being killed - you cannot run out now!
Note: The TankCrew mission will not be running whilst we are doing the regular Sunday/Tuesday Coops, the PWCG campaign, and any other special/custom stuff being created and hosted in between - like on a Saturtankday ... well, no problem, you won't miss that Tankcrew mission, as you are joining the event, for sure!
Have Fun!
Edit by Friar - The first couple of rows of targets now re-spawn so you will not be able to kill EVERYTHING!
