This page contains map tile layouts for use with custom scenarios. These were created using the Zombicide Map Editor. My apologies for the "dimness" of the graphics, but these are the tile graphics which CMON makes available for the generic 3rd-party map editor.
Achtung: this page uses webp-format graphics to minimize data traffic and the SCM repository size, but only modern browsers (as of late 2019) support it.
