This platinum save set will get you all of the achievements for the game with some work on your part.
You will have to play the story mode of each faction fully as i can not set up the story properly. It will take you a few hours to beat each story.
you can play on any difficulty. be sure to play the story in this order,(Wei,Wu,Shu and lastly jin) so you can avoid a know glitch.
I have fully detailed instructions in each folder and also make sure you unlock the achievements in the order that is stated, as getting later achievement early would be bad.
The kills in 1 battle and other miscellaneous achievement you will have to do on your own as you can not set them up.
You will be able to easily get those achievements with any of the later saves.
DW7 Platinum Save Set
I hope you enjoy and let me know if there are any problems.
