Hey there
I don't know if somebody has already found a solution, but here is mine regarding the Armstrong Canon having no impact sound:
1. Open the darthmod_shogun.pack in your Shogun 2 data directory (you need the Pack File Manager: http://www.twcenter.net/forums/showt...Features-added).
2. Uncheck "CA Packs are read only" in the rooster "Options" and confirm that you're not a coward .
3. Go to darthmod_shogun.pack -> db -> projectiles_tables
4. Find the row which has "boshin_armstrong_gun_shell" in the first spot.
5. Go to the entry "boshin_armstrong_gun_shell" and change it to "boshin_parrot_gun_shell"
6. Go to file -> save.
And now you should be ready to go
