My initial thoughts were to bring Redcap Rodney and Nelly the barmaid.
Redcap Rodney is a Fatty killer for sure with his +1 damage and has proved to be a great addition early in the game. I have been trying to open at least two doors in the first turn and this reveals many rooms worth of zombies. All will be moving towards the survivors who are poorly equipped until they start searching. The first aim is to clear a square that will allow others to search and pray for some decent weapons. Redcap can handle a fatty even with his starting weaponry and this has been required on more than one occasion.
|Nelly the Barmaid|
Nelly is a speed merchant and I have been using her to open the more distant door. She can retreat to join the others. Her added mobility can often be needed to give much needed support or to hold a position and then run when required.
All in all I think that they should play well together and I am looking forward to giving them a try.
