I just finished the mission "Evangelist" but i died as the Eva exploded. the next mission starts up and I cant do anything cause I'm dead!!!
Is there some way to hack the save game file so I can redo the last mission and not die???
thanks for your help

er... if you died you shouldn't be able to go to the next mission unless you failed 5 times and it gives you the option of skipping. If you somehow went ahead while dead... then, well, I have no idea what you did. You should have to repeat the mission. you might be able to use FRED to manually change some settings, but I don't know enough to tell you how.

I'm not entirely sure of things, but if FS1 and FS2 are similar enough, the following trick might work.
Get a tool that can open .vp files. VPView is a popular choice.
Use the tool to go through the .vp files in your \freespace\ folder and find the one that has mission files.
Extract this particular mission (or everyone if you're uncertain) to some location on your computer.
Open this particular red-alert mission (Doomsday) with Notepad or equivalent.
Fidn the line that says "+Red Alert: 1" and change it to "+Red Alert: 0", without quotations.
Save the changes and place the modified mission file to \freespace2\data\missions (NOT back into the .vp!).
The mission should now start without the red-alert status, with your ship intact and possibly with a chance to change your loadout.

thanks for the ideas, doesn't seem to work though :(
Its in Freespace 1.
It wont let me repeat the mission as its saved as soon as you complete a mission.
And although I'm dead apparently I still finished the mission ?!?!
Any one have a save game just after or around "Evangelist"?

Sorry for late post but this is important IMO:
NEVER TAKE THE OPTION TO SKIP A MISSION IF THE NEXT IS A RED ALERT MISSION!
It WILL screw the game up, even in the SCP verison last time I checked. Someone should submit that to bugzilla...
EDIT:
If you're stuck with being unable to revert to the past mission there is little you can do past trying to edit the pilot files (not recommended), if that fails all that's left is to reset the campaign. It sucks I know. :(
