We would need organization for this kind of work as our combined knowledge would be best. What is obvious is that the maps need to be aligned and some missing areas need to be constructed, as an extension, and to facilitate save passage to the next area/mission. 3D modeling, editor, scripting and texture work is required. This is what our Engineering office is for.
The in-game map might be a bit tricky...
Please share your ideas on the suggested missions by Stern.
Please add any other ideas you have in mind about other missions.
It would be best to try the easiest missions to merge, then decide what needs to be done. After that, possible work can be divided between engineers based on interest and skill level
We can do it gentlemen!
