The White Box Companion for Swords & Wizardry was just released by Barrel Rider Games "introducing five new classes: Bard, Druid, Paladin, Ranger and Thief. While none of these classes were around in 1974, White Box Companion streamlines each of them and adds new options for players while keeping the same simplicity and elegance of Swords & Wizardry White Box. All in an easy to read 16-page digest format!"
