Strategy
Rock Factory launches one Asteroid at the start of every turn, allowing you to clutter up the midrow quite well and defend yourself. You will need a way to use all the produced asteroids effectively (Droneshift/Evade), and note that launching one isn't optional; if you're not careful you can destroy other asteroids or even your drones this way, and leave your missile bay vulnerable.
Note that if you get 2 stacks of Rock Factory and your missile bay doesn't have any midrow objects in front of it, the second asteroid launched will destroy the first launched and itself, making both useless... most of the time. However, if you have Gravel Recycler, this means you'll get 2 Temporary Shield per turn. If you have Salvage Arm, this means you'll get two Energy per turn - both very strong effects!
Its A upgrade makes it 0 cost, which is a solid tempo upgrade.
Its B upgrade adds 2 immediate asteroids, frontloading the value of this card and giving you defense the turn it's played (and if you have Gravel Recycler or Salvage Arm, you'll often be able to get value out of those artifacts).
