UPDATE:
I have packed up all the current progress into a ZIP(dropbox)
This is the >DEMO< of the map, and only the map.

Here is the Screen Shot Catalog so you can look at all the highlights of exploring and creating the map!

Description
Last Bastion is a key note in my current work in a (Story based) MAP and MOD pack. Two great tastes made to taste great together.

The map features a little back story, and a minimalist approach to a custom-designed warzone, reducing clutter and increasing the Vanilla Spades atmosphere.

Structures!

Minimizing Detail! (While keeping logical supports and firing lanes.)

Buildings!

Clearly marked, predefined underground passages!

Stairs that don't suck!

But to really drop you into the Last Bastion mind set, i will also include a modification to the origional AOS weapons and equipments where applicable.

New Guns!

So to wrap this up, I have written to top off the final release with a text file that will include a tiny piece of back story and the inspiration to what leads me down the path to introduce my DOOM2.WAD design skills into a new area, Voxel editing. I will work on this as often as i can allow my self. I'll up date this thread if any thing truly worth posting about comes up while I'm working.
