Okay, I've spent an hour in the forums trying to figure out how to get/upload/play off line a staged mission. I'm stumped. I tried to go to 00Cougan's page and down load a .res file for 2.28, which I could do, and placed it in the misres directory. But the terrain link on his site is broken. I don't have the Resource Uploader (do I need this?). I'm actually running the most up to date version of AH, btw, not 2.28. So, I'm completely confused on how to get staged missions to play in off-line play.
99% of the stuff out there is out-dated and pre-date staged missions before they changed over from offline missions only...
Many of the old missions have to be loaded into the mission editor and re-saved under the new format, but has failed in many ways...
Currently your best bet is to open up a custom arena and sift through missions that peak your interest, then you can even download them for yourself and have happy time offline...
OR
You can get a hold of someone who is actively building missions and make a request...
OR
the best one of all, you can make some yourself... I do have a tutorial available on the prime basics... Also, like above, you can get a hold of active mission builders to teach you....
