You don't really need a new install unless you got other mods running as the gameplay changes are all in two files.
Ok, tell me if this one is good enough for you.

Installation instructions.

1) Make a backup of your CRUSADERS_UNIT_PROD11.TXT, CRUSADER_BUILD_PROD13.TXT and PROJECTILESTATS.TXT (this one only if you plan to play other mods that uses the ninjastar as composite bow, otherwise it won't change the game).

2) Extract CRUSADERS_UNIT_PROD11.TXT, CRUSADER_BUILD_PROD13.TXT and PROJECTILESTATS.TXT to your Total War folder (usually C:\Program Files\Total War\Medieval - Total War).

3) Extract ZXMOD.txt to your \campmap\startpos folder.

This way you'll get a second Early campaign (will change it later) that you can recognize because of the changed land ownership.

How to uninstall/restore:

1) Copy your old CRUSADERS_UNIT_PROD11.TXT, CRUSADER_BUILD_PROD13.TXT and PROJECTILESTATS.TXT over the modified ones (just overwrite them).

2) Delete ZXMOD.txt from your \campmap\startpos folder.

Have fun and hope to hear feedback from you soon!
