Certain refit kits require that you use a Factory to install them. Additionally, according to StratOps, a Factory gives a -4 bonus to TNs to repair mechs. I have a player who wants to take advantage of this bonus, and I cant blame him, I'd want such a bonus myself.
Question: Are there rules ANYWHERE for this type of thing? Any references that could be suggested that could help me formulate a more complete house rule on "advanced repair shops" or the like?
