unlocking more costumes

I recently was curious how you're supposed to unlock more characters.Now obviously,when you beat the game for the first time, you unlock a bunch of characters.I did that,but then I unlocked a fw more characters.At first I didn't know what I was doing to make that happen,but I finally figured it out yesterday.To unlock the daimyos (they come with their main generals when unlocked),you have to enter a mission where the goal is NOT to kill that daimyo,you have to kill them,and then you hsve to carry their corpse to the exit. NOTE: You will fail the mission unless it's a reconnaissance mission.To unlock the leaders of the mosu ninja clan,the leader of the kenobi clan,and many other characters you have to make the story play out differently by choosing a different mission when you only have two to choose from.And finally to unlock Zen's different costumes you have to do the story on different difficulties and beat it. P.S.-you can also carry other peoples' bodies to the exit.
I hope this helped all of you out there that don't know how to unlock characters in this game.If any of you have information on this topic that I didn't include,be sure to post it.
