I like he WH campaign, but I think something has to change.
1-01 isn’t a bad mod, but it doesn’t really bring an intro feel to the game. 1-01 feels more like a mid season episode of a show.
1-02 has a much more intro feel. It feel more like the season pilot.
See where this is going?
I propose changing the beginning of Mod 1-2 to the players go after kids and ends with them finding one still missing. Mod 1-01 can then be run as the second mod. The writers would have to do a few rewrites to make it work, but I think it could really make the campaign work better.
