I have been working on an expansion rulebook for Giants: The Action Figure Game of Colossal Combat. As I develop the rules for the expansion, I will frequently share playtest files to the game's Facebook page.
The most recent playtest rules I have posted are the solo rules. These rules pit a giant against a military force as it tries to destroy a city or retrieve hidden objectives.
You can find the post about the solo rules here:

For those of you who have never heard of Giants: The Action Figure Game of Colossal Combat, it is a miniatures game that allows you to use action figures as the combatants in an environment meant to be destroyed. The primary focus is on kaiju and mecha battles, but the rules can also be used to recreate other types of battles. The game is an evolution of my previous game Giant Monster Rampage.
