More about this stuff:
If you missed the two Kickstarters you have to go through 4tk. If there is a downside to this stuff it is that it is 'too modular'. Everything can be punched out, so you can end up with too many holes. You may be advised to use some glue. Still its a fraction of the price of similar products though clearly not as good quality as Antonecitis Workshop and others of similar size and scale. I think this set works best as hab slums or frontier settlements.
However it does have infinity in mind from the offset, with add ons to goth it up.
Now this is excellent value if you buy now. Check out the stretch goals, they include a not-Leman Russ IFV and other bitz. For Infinity you can only really choose the 'Cobalt Factory' industrial set. Otherwise its great for 40k
