Hi Jason,

Thanks for the compliments! To answer your questions:

- Most of the levels use blocks, however some of the areas not featured in the demo are model based. It really depends on the type of area. I've found that indoor areas like the prison tend to work best with blocks, whereas other areas, such as caves and tunnels, work better with models.

- I am using a normalmapping shader (with specularity), a few metal shaders, and a water shader.

- No detailmapping is being used as of yet.

- I'm using the latest version of A7.
