Give the player the ability to control a clay man so they can join in the fight to, instead of just watching!
Love the mod and good luck!
Cool, until you end up as the person who needs to put that in the game.
Then not so cool.
On the other hand, you can use the 1.6.4 version of clay soldiers along with guliver mod to fight with clay soldiers at the same size, though you'd still one-shot them and only be able to fight zombified soldiers.
That said, I personally think that it would be nice if we couldn't one-shot a soldier with our bare hands, and instead needed a tool to do that, like maybe we need to hit them with the clay disruptor to kill them one-hit.
