Download the SimMars region pack and add 7 new exciting regions to your game! All regions have been rendered from real Mars height maps and represent existing geographical locations. The pack comes with an installer and automatically installs in the correct folder. SimMars Beta 3 is required. If you are on a slow internet connection and downloading large files is unpractical you can still enjoy those maps by rendering them yourself within the game. To do this follow the instructions in the ReadMe file of SimMars Beta 3.
