Tried the mission on hard mode. Here's a summary of my attempts:
1: Poked around at the map, surveyed all mining locations, checked enemy starting behavior.
2: Tried to build a tube out to the 3-bar mine. Enemy attack arrived right as that mine was getting online.
3: Built structures along ore hauling path for free bulldozing. Killed by a meteor that destroyed both a Tokamak and a University on that path.
4: Built then dismantled the Light Post that comes with the base to accelerate Standard Lab construction. Did not have time to research, much less produce, lynxes in time for enemy attack.
5: Skipped Cybernetic Teleoperation in favor of getting Laser posts sooner, placing them in the direction I saw the opponent attack from. Built Smelter right next to mine to secure more income earlier. Survived the first three laser-only attacks. Died when I had an inferior number of laser lynxes up against a mixed army of laser, railgun, and EMP for the fourth wave. Might have stood a chance were it not for a meteor that killed an Agridome and disabled the vehicle factory until it was replaced.
6: Tried tube cutting the Vehicle Factory. Learned that walls built on tubes magically disappear. Learned that the AI sometimes, but not always, is smart enough to push a unit that is on the intended building site for a tube off of it. Was able to delay enemy Lynx production so long the second Lynx to come out was a EMP one (despite the Advanced Lab having never received tube connection.) Was able to survive the first, smaller-than-intended attack, but died thereafter.
7: Used the Robo-Surveyor to assist in holding the tube cut, and got Laser tech early-ish into the game in order to build a laser guard post in range of the enemy CC. With the enemy defeated, getting my 40 population colony to gain population in the face of the natural disasters tanking morale all the time was not straightforward. I built a CC and structure factory in the enemy base to take its rare. This also really helped when a supermassive earthquake destroyed 2 Smelters, a Spaceport, 2 Tokamaks, and about 6 morale structures at around mark 1200. Final completion was at mark 1568. By comparison, my fastest Hard mode Eden Starship colony mission time is 1317.
As far as the disasters themselves are concerned, I already knew but this mission confirmed that I really just don't like big meteors. Keeping vortices confined to the middle of the map is good. One feature I would like to have if I made a multiplayer map is for any disasters that land near my base to also have happened with similar severity near the enemy base at around the same time frame.
