I managed to finish an old half-finished map I had sitting around on my computer collecting virtual dust after I got inspired by how healthy and active the community still is after all these years. I've fallen in love with the new tools too, so hopefully there will be more maps after this!
Although this map is based on DM6 - The Dark Zone, it's hard to make out any of the original elements, as I changed the map so much to make way for a compelling single player experience. All skill levels are supported, along with (untested) coop and deathmatch modes.
