The lack of map/mod allowing us to admire the new areas offered by our friends is struggling. Fortunately, Napalm_Isis was here to provide us all the required informations about Far Far Range prior 1.4.
And here is the small stone I'm adding to this masterpiece : a full map of what Viktor's Experimental Update brought to us :
Location of Viktor's Workshop relative to the Slimeulation is inaccurate

Since you cannot take anything from the Slimeulation, I've only showed Exit portals, Debug Spray and Treasure Pods locations. It may not be perfectly accurate, but precise enough to satisfy anyone (especially someone willing to create a Slime Rancher Full Map Mod ;) ).

And here's what it looks like when you mix everything together:
Again, location of both Viktor's Workshop and the Slimeulation relative to the other islands is inaccurate

If you want to see foods, resources and other stuff locations, please do check the original Ultimate Map by Napalm_Isis.

Some stuff are still missing, like DLC content, but I'm too lazy to create yet another map for this :D
