Okay, I'm sure this is an easy question, but I'm just too freaking lazy to look it up.

I was under the impression that in order to break a segment a wall down, your fig needs to be in square next to it, and have a printed attack value of three or higher. I was playing someone, he perplexed his damage up to three to break the wall down. I protested, but I didn't bring a rule book with, so I let it go.

Also, I couldn't remember, you can charge and break down a wall right?

All you need to break a wall is to hit it for 3 in one shot. This can be ranged or close combat. If you BCF the wall, you must roll damage and get higher then 2.

Okay, thanks. Is this a new rule (about the non-printed damage)? I could have swore that it needed to be printed value of three. Guess I was wrong...won't be the last time.

As of the Indy rules (I have pretty much forgotten anything prior, so I don't recall anything before that), all you needed was the ability to deal 3 damage. As such, figures with RCE/CCE could use that power to be able to break walls. Perplex is also a viable option. And yes, BCF does need to roll to see if it deals enough damaged to the wall.
