Hmm, no feedback here at all?
Probably because the mission can't be played. The filename is incorrect thus it won't show up in the mission selection screen. The filename is GCI_Mission_1.pbo when it should be GCI_Mission_1.Chernarus.pbo. We were planning to give this mission a try today in our group, but I noticed this issue and couldn't bother restarting the server with the correct filename, so we played some other missions instead...
I will post some feedback once we actually get to play this mission next time.
Update: Well, we got to play it now. I've got to say that the mission is really confusing. The briefing seems really unfinished - no markers, not really any tasks assigned, no intel, nothing.
When we got on to the mission itself, as HALO jumpers, we started inside the plane, traveling to an unknown destination. We decided to stay inside, in case there was an auto jump or at least a message from the pilot when we're at the drop zone. Suddenly the plane exploded and we respawned at some random friendly base with fire fighting going on. We restarted the mission soon after.
This time, we jumped before the plane exploded in mid-air and ended up spread out in a forest near the South-Western coast. We ran into some enemy patrols but got killed after some while. At this point, we decided to end the mission because it wasn't really clear what to do...
