Below are some screenshots from a few new objects.

Modern houses:
There are 8 fully destructable suburban houses to create urban environments. There are also some other urban decoration objects planned.

New barricades
There are some new barricades and decorative objects to create something like a shooting range.

Trenches
This is the main reason why the update takes so long. This has been a highly requested feature, which is quite difficult to implement, but I'm on it and the progress is looking good so far.
