My review of Shadowrun 6th Ed is coming, but here is something I think will help.
MODIFICATION CAPACITY AVAIL COST
Plating [Rating] [Rating] x 2 Rating x 2000¥
Plating armors up a suit of armor. The armor increases the soak roll by a value equal to its rating. Each time the suit of armor absorbs damage, reduce rating this modification by one.
Thoughts?
