Yeah, the name is real ;-) I'm on Facebook, EM4 - Italian Submod, Connor Brumleve. Chris07, nice advise, I'll try that, it's much simpler. But you know, the air counter is much cooler than the 100-0% icons.
I would add the mission script in Scripts/Game/Mission/fp_freeplay (I think that's the file name)... But it still doesn't work, so....
Thanks everybody
