So, let me get this straight - Spoilers got to the Sol system, and started wreaking havoc (A terraforming base near Jupiter... So, the Not-the-player tried to terraform Jupiter?)
No, not really, I basically adapted the plot of the famous series Battleship Yamato to fit Aurora rules. It goes more like this:
- The Sol invaders (called Gamilas) are just an NPR, albeit much more advanced thanks to living near another alien race who achieved TL12.
- The terraforming base is an orbital (...a huge/continental one), and just like in the series, it is parked there in preparation to terraform Earth for the Gamilas, which btw. is already a dead wasteland from bombardment at the start of the show.
- Not-the-player is just a thin alias that the player uses in hopes of disguising his beginner mistakes to the dismayed captain.

- 62kt is the accurate size of the Yamato Battleship
Had several size 3 missile launchers, but no missiles... No magazines either.
No powerplant and badly tuned Beam-FCs as well. ...Until the C# refactor that is.
Finally, that spinal mount with a huge damage... It backfired somehow?
No, it worked. ..I feel like explaining jokes. Advanced lasers in Aurora are deceptive, because when you get them, their first 2 tech levels list 0 damage. However, it picks up quickly after this, especially when their caliber is enhanced by the spinal weapon multiplier, leading to the most surprisingly devastating weapon in the game.
So the Aurora Battleship, after all these design issues, this cavalcade of weapon failures, -a lot of 0 damage guns if you will-, it was the
actual 0 damage gun that instead did the literal opposite, -doing the highest damage possible- and oblierating not only the target ship but also the whole base behind it.
The captain feels like upside down world after the ordeal. Who can blame him?

(btw. I find Hawking Radiation to be superb explanation for what makes the laser-light production so "advanced" here. Of course to get some usable micro black-holes, you'd need a larger gun to even get the motor started, but once it starts...)
I highly recommend the series to Aurora fans, because the tech feels much like Aurora in most regards. The ship designs shown there (except for Yamato itself - too water naval) are often candidate for what I imagine my ships look like. You can find it on 9anime.to under the name "Star Blazers: Battleship Yamato 2199" currently.
