What do you think about adding a logical sequence to the merchant missions, where they follow a story, having a final objective, with the possibility of each new Alpha being a season?
For example, missions could follow a story of searching for information on the whereabouts of Dr. "X", who was working on a cure for the virus before his disappearance. Mission 1 would be to go to his house, where the address of his secret laboratory would be discovered. The next mission would be to go to the laboratory, where it would be discovered that in fact that was never the right place and that Dr. "X" worked in a place monitored by the government. In the next task we would find the location, but the safe with valuable information could only be opened with a key that would be in Professor "Y's" house, which would continue the story. Finally, in the last mission it is discovered that Dr. "X" may be alive in a refugee camp, leaving the bridge for the next season.
If you think the idea is good, please help me upload this topic and develop the story.
NOTE. Sorry for the bad English, google translation
