Ensure Dad has a Father’s Day he’ll never forget with free unlimited combat this Sunday, June 16, 2013. Dads play free with paying son or daughter. Everyone must be a registered customer and at least one member of the party must “Like” Hard Knocks on Facebook to qualify. Also, catch the normally locked mission Bloodline for a one of a kind family combat experience. We’ll be open from 1PM-9PM so don’t miss out.
