THE WORLD
HAS SOURCES.

Map data overview

Source maps inherited from the OpenFront map generator are licensed under CC BY-SA 4.0. Attribution and share-alike terms apply when the game is distributed with them.

Greece, Yugoslavia, USA and Egypt were built for New Game+ using Natural Earth 1:10m vectors (public domain) and AWS Open Data Terrain Tiles. Terrain credits include SRTM and GMTED2010 data courtesy of the U.S. Geological Survey, Global ETOPO1 data from NOAA, and—for European maps—Copernicus-funded EU-DEM layers.

Climate data for Switzerland, Greece, Yugoslavia, USA and Egypt derives from Beck et al., “Present and future Köppen-Geiger climate classification maps at 1-km resolution,” Scientific Data 5, 180214 (2018), doi:10.1038/sdata.2018.214; data doi:10.6084/m9.figshare.6396959, licensed CC BY 4.0. Climate classes were converted into moisture values, reprojected and smoothed.

Egypt’s optional real-map colour data derives from NASA Blue Marble Next Generation imagery by Reto Stöckli, NASA Earth Observatory, served by NASA GIBS. The imagery was reprojected and modified for the game’s terrain grid.
