I just have to add some more labels for the rivers and other terrain features.....and maybe figure out some roads, as I only have the rail lines on (and put roads with them)
The black hexes are impassable because the map I ummm....'borrowed' from has a different hex configuration. ( it goes up down up down instead of down up down up).
The terrain looks this way because I am using a meld of RedMarkus' mod, with um....bits of Krupp thrown in.
