Exactly what it says on the tin.

Just a tiny little mod that can spice up Adventure Mode a bit. It adds race-specific battlecries to the vanilla races (no distracting splash screens, just quotes showing up in the combat log).

So there's one set of quotes for dwarves fighting elves, another for elves fighting humans, etc...

There aren't too many quotes yet (it's just to demonstrate the principle), but I expect some creative types roaming the forums will be able to come up with better variety later. More importantly, I expect other modders would like to use the same principle to spice up their own mods. Feel free to do so!
