Adventures are self-contained modules for The Witcher. Some are released by CD Projekt RED, while others are self-published. Modules released by CD Projekt RED are usually called premium modules and are voice-acted, but the only real differences are whether or not actual paid staff from CD Projekt RED worked on the project and with original voice-acting.
Several adventures are now available for The Witcher. These include:
Most of the adventures were announced and hosted for download on the official Witcher site, five of them were integrated into the 1.5 patch.
