Angels and Archangels
 

hope they include this two units..(^_^) .V..

and enhance the spirits animations..like in final fantasy..

Sorry to be pessimistic, but I would suggest you to rather then "hoping" will find out how to create video/audio and all what is needed in KB tL modding -> I am sure you can start by downloading Army of Darkness MOD - where are unique units, you can also browse this threads in MOD folder -> as here is already a lot written about modding.

So you will be prepared when the Expansion arises... help yourself and even god will help you (or not)
