Printed out the Mansion and mutation cards and played a few games. The mutation is great, I would love to see cards with effects themed for this mechanic. A mansion with all infected having effects is great design as well. Favorite being the Los Illuminatos Shield, had a guy go in with one gun at 90 Damage saying "Whatever it is its dead!" and flipped that. The effects shook up typical game plans big time and gave a whole new experience. Now I really hope this isn't the last we will see of this.
