I'm going to try out the Wulfen campaign with a friend of mine!
But, there's a slight problem. Namely, some of the mission rules conflict with certain mandatory formation rules that I might want to take.
To be more specific:
In the mission, "As Above, So Below," the game is played on two separate boards, each a 24x72" segment. (The turns are played simultaneously.) The Space Wolf player is required to deploy all of his vehicles on one board, and all of his infantry on the other board. (The fluff explanation being that the one board is above ground, where the atmosphere is toxic, and the other board is below ground, where most Marine vehicles wouldn't fit.)
The only list requirements are that the Space Wolf player ONLY bring models with the Space Wolf faction.
However, this creates a problem: Several formations found within the supplement book, Champions of Fenris, require certain models to begin the game deployed inside vehicles. (Namely, a couple Terminator formations.) There are three possible interpretations I see:
One, Mission trumps Formation, the models have to be deployed outside of their transport.
Two, Formation trumps Mission, the models have to be deployed inside of their transport.
Three, a Paradox is formed, the formations simply can't be taken.
