In an effort to make your 6mm battlefields more interesting to look at, I have released some 6mm sci-fi cargo containers.
They are meant as shipping containers, but they can also be used as temporary dwellings. When I get a chance, I will have some gangways and ladders made that you can use, if you want to make them into a rough settlement.
Now, I know they do not make a lot of sense in terms of 'realistic' function, but that is not why I did them. I wanted something that could be used to represent futuristic cargo containers - it is clear from looking at these what are they are meant to be. That is what I wanted, that is what we have, models to represent something, nothing more, nothing less! 
Anyway, they are on the website now.
I will be starting on Project Junkers next, so keep tuned.
