Hey wow, that was a really cool idea. :D these'll be good for warrior replacements!

An in-game preview would be cool...

Looks good in a first look, but there's no credits file in the zip.
Do try to remember people will dload all sorts of stuff and then forget who the creator was. Especially since this doesn't include embryodead's name in the zip title.
