So the enemy flyby ships that pelt you with missiles can now be taken down, the Blaster is currently the most effective weapon. You get a fair amount of XP too, although from the video there may be some kind of glitch with it, or I had the first level's XP requirement set lower than I thought. I'm also rejuggling the reward credits from enemies, doubling some of the values.
Now I need to design a new auto-weapon replacing the chaingun weapon, something different, we'll see what I come up with.
Also the first mini-boss has been designed, a deadly hover-capable ship that has a gatling gun, twin missile launchers and can drop enemy droids.
With the wonderful use of the EDuke32's clipshape feature I have all the voxel models with fairly decent collision detection, you can even fall through the craft's hover holes.
