It seems SanAndreas.de, the ‘official’ german website for San Andreas revealed more of the map than they were supposed to! Earlier today the main flash clip with Cesar would also allow you to see the Las Venturas area, now the mistake has been corrected.
Unfortunately, we can no longer show you the images, and R* confirmed that the map is NOT accurate.
As you can probably figure out from looking at it – that isn’t the real Las Venturas map. It is a placeholder workfile block that got thrown up there and somehow made it on the German site.
