A Base at my hometown with a big area of surface tiles.
For the included scenario you need to download:
Universal Remote Manipulator System: http://www.orbithangar.com/download.php?ID=3373
Shuttle tow vehicle: http://www.orbithangar.com/download.php?ID=1335
XR1 and XR2: http://www.alteaaerospace.com/index-3.html
If you want a bigger surface tiled area download my Central Europe Surface TIles (but they need a long time to load).
