One of my many brilliant ideas in the realm of evil DMing science is resort wars. Where the party in question takes sides of a conflict where two hot spring resort towns are on the opposite sides of a large mountain lake (think Lake Tahoe). So naturally the towns need merc groups to do all of the dirty work of sabotage, raids, kidnappings, assassinations, and so forth. Of which they get paid handsomely and get free perks with food, whores, and all the delicious hot spring bathes they could want.
These merc groups operate under their own authority, since then there isn't any paper trail for opposing spies to use as counter intelligence. Random acts of violence and malice is the best way to go about things, the trick is that the chances of you getting safely to the other town is quite slim. So most of the combat is going to be in the woods sneaking about or attacking cargo trains. Naturally keeping any enemies you find alive, especially cute girls, is always appreciated for the sex slavery trade in the resort town.
