Ok i tried searching the web and hot scripts but i can't just find what i want free
What i need is:

1- A login script along with a register option. The script must also be able to update and edit database.

2-A data base for acounts which can hold unit status and traits.

3-A battle engine script that can be edited.

4-A cool template with dark colors (black,brown,night....)

Also can you tell me how to integrate them into my sight? do i just upload them to the data base or something?
Thanks for those who try to help
