I figure I'll start here and make my way around the net if I'm unable to find help.

I've beaten PotMN and have Master Ninja of Missions, but the survival missions give me a bit of a problem. I don't use any weapons save for the DS, ES, and LS. If anyone has any good strategies for the flails, talons, kusari-gama, BotA, or tonfas, I'd appreciate it. Getting 1.5 mil isn't too difficult (save for the flails, because they do almost no damage to enemies) but the last 500k-ish is ridiculous, as I usually get slammed with the large, flying mechs with blades and the red gajas.

Also, if anyone needs help with Master Ninja or any other missions, send me a message over XBL or post here and I'll do what I can to put you on the right path. :)

Sorry I cant help but I'm on my mentor playthrough and since youve been there and done that I could use help.

I'm sure there are different strategies for the bosses and thats mainly what i need help with. Particularly the boss of the third stage. That stupid silverfish like boss. I hate him!

All I did was use the Lunar Staff's 360UT while standing in the middle of the room. Anytime he shoots anything at you or he gets close, just let off the Y button and start spinning around. You'll avoid almost every attack completely and have time to reposition yourself. Also, you're invulnerable during the whole thing, so if you hit him, you're doing damage while taking none. :)

If he flips and starts riding along the ceiling, you can attack him normally and take no damage as well. Good luck and let me know if you get stuck again or need any other help.

I'm on my Mentor run at the end of chapter 5 right now.  I've played the mission and I cant imagine how difficult it is to beat them on MN.  Especially mission 14.  that one gave me the biggest problems.  At least I know that it is possible to beat them...  I might hit you up for some tips sometime. 

(Big thanks to Reim for his vids on youtube... much help on the playthrough so far!)
