If I had to rate the progress of the WCHF demo from 0-100%, I'd say the demo is at 70%.
Kilrathi ships update: Thanks to JasonRocZ, I now have a Ralaxath model! The geometry was cleaned up, details were added, and the whole model was remapped from scratch. The Ralaxath was the last Kilrathi ship I was waiting on for the demo.
Landreich ships update: All of the Landreich fighters and capships that will be used in the demo are now in place. The fighters may need to get recoloured to be accurate to the Landreich colours in FA, and the Scimitar texture will need to be redone at some point. The Wake and Exeter will need to get returreted, recoloured, and rebalanced. But other than that, the fighters are balanced and usable.
