- Advanced Cannons added (normal and large cannons)
- Advanced Ammo added for use in the advanced cannons
- Advanced Ammo Factory added to produce the advanced ammo. It consumes steel and sulfur.
- Advanced Fire Extinguisher added. It's more effective at helping your crew to put out fires.

- Fixed some errors in the naming of some of the asteroids (instead of Ag for silver, I had used As which is a totally different element). The asteroids themselves are not changed.
