A great book with all the information needed to play the game. Even if a player has the box sets, I recommned buying this book.
This product really sells itself.
Very good looking and professionally laid out.
Highly recommended if you are interested in Battletech.
This is an excellent update to the Battletech rules, it clearly codifies what people who are playing need to know. It could do with a batch of training scenarios, but then again if it did no one would need to buy the box set, LOL.
