Hey there :-)
I wasted a lot of time (ok, didn't waste it actually) reading all the topics about the jetpack thing :-)
The rest of my time got straight into browsing the games files.
Today, while searching inside the .rpf archives I found some things I want to share with you:
This file includes a texture of runes (Sorry when this has already been found ingame)
We all know, there are aliens in the game, I don't know how to open this file..
Don't know what file type that might be, but alien camp? Would be nice
I found "scenario" waypoints for the alien camp.
<min x="2073.047363" y="3523.482178" z="31.900034" w="0.000000" />
<max x="2849.520752" y="4371.533203" z="101.107513" w="0.000000" />
I don't know, where this is, but as I'm typing i keep thinking the devs mean the alien worship hill in the desert... :-(
Texture file with interesting file name...
Inside are two graphics, prop_chrome_dirty_02 and prop_wood_plank_05
Both show exactly what the filenames tell you.
Now THIS is interesting! If someone could tell me how to open this files :-)
The radio talks about some apocalypse with asteroids coming to the earth
Could it be the merryweather weapon?
Probably the most interesting file I found today.
It comes along in an folder with veh_cars veh_trains veh_tank and other files of vehicles in the game.
Seems we can use the ufo after all, but could also mean it counts as vehicle but isn't usable for players...
If someone knows how to open the specific files above, please message me :-)
Btw: No signs of jetpack so far, I also haven't found the ufo sounds that come up when going near it (before it shuts down your chopper). The name of the soundfile might give more details on how it is named in the files to find references to it...
