Thanks for posting your game!
I have some questions about Keywords and Hardness Values:
1. Are there suggested Hardness values for terrain elements? In your reference art you have a picture of the Rhino (seems like a great example of a Big Guy with Hardness 5), how would he stack up compared to common things like Cars, Ruined Walls, and Jersey Barriers?
2. What counts as a Trap? Is that related to the Remote Explosive item?
3. How do you Carry an item to use it as a shield from slam damage? Does that refer to the Tools of the Trade items, or a small terrain like tires and manhole covers?
