Somebody is back from the grave — Somebody bad Somebody who should have stayed dead — Somebody who didn't Somebody who wants to get even with the agents of this defeat — Somebody with a terrible plan: The Deadwave. ◊ Deadwave is Mark Morrison's classic Call of Cthulhu scenario of zombie-fuelled revenge from beyond the grave. Designed to be woven into the fabric of an ongoing campaign, it offers a detailed yet flexible template from which a Keeper can easily create a memorable and deadly adventure. ◊ This time, it's not in some terrible Mansion of Madness that the horror will be found ... it will come for the Investigators in their own homes! ◊ Deadwave is written in a unique format which can be easily run in any of the three major Call of Cthulhu era — classic 1920s, Gaslight-era London, or modern day. Separate handout sets are provided for each, capturing the unique look-and-feel of the era. Originally written in 1994 and published in the (text-based) online Chaosium Digest, this version entirely revamps and expands Mark Morrison's original manuscript text, sets it amid flavour-rich art and formatting, and adds period-authentic prop-quality handouts.
