After you fixed the turret spawn I just wanted to share my experience using the recommended "death world" settings (no water between hexes, starter turrets enabled as well as cranking biter spawner occurence to 600%) so far.
The beginning is horrendous, you're basically just rushing grenades before the turrets run out of piercing ammo (I appreciate you making them epic quality btw). Because ore is mixed you can effectively never gain net positive iron after subtracting iron spent on killing biters with yellow ammo. I had to handmine close to a thousand ore to avoid producing pollution via mining and stretch the red ammo until green science. There was a nearby trade giving yellow ammo in exchange for hazard concrete but I felt like that would have been cheating as it spawns everywhere on the ground.
Researching grenades give you some room to breathe, you can now wall yourself in and mine the shit out of the starter hex's ore to sift for iron, lobbing grenades at any biter hordes that attack. Armed with a shotgun and some fish - bought for amounts of copper wire that would make any grown Romanian cry - you can take out your first nests to discover more trades and finish some quests, the only time you get to interact with the mod 5 hours in. The modular armor and bots are very nice I will admit, though if I had to make a suggestion I'd appreciate if the quest gave 2 roboports and 20 bots, 10 are too little and move too slowly to be of much use besides building a proper furnace stack. Or hell, maybe an energy shield to make clearing nests at this stage in the game easier. My next ambition was unlocking flamethrowers to reduce time spent running around repairing walls and grenading biters.
With flamers unlocked also comes a new way of killing nests: Flamethrower crawl, also known as the KFC deep fryer strat. Expanding my base (that had run out of iron ore at this point) a bit this way I found a trade giving iron ore from copper ore, a couple of iron plates, and explosives. Finally, a coal sink. Also a trade for coins from just plastic, which I promptly started producing as well. Currently, sci wise I just unlocked laser turrets and am working towards researching construction bots so I don't have to repair my walls and turrets by hand, maybe then I can try taking on a dungeon or two before aiming for a rocket silo next.
Even with all my gripes about the early game I like it so fair, it's pogging to find a good trade somewhere and automate the trading process. I'd like to see more unique buffs added to items in the catalog, and maybe redo some useless ones. Perhaps instead of a 5% hand mining speed buff from enhancing ore you could make mining drills work faster/gain productivity? Same for assemblers and crafting speed upgrades. My last suggestion would be increasing the iron ore to copper ore ratio in the starter hex, at least on hard mode. By the time my starter patch ran dry I had around 10 iron chests worth of copper ore sitting around, as I didn't get a decent copper sink trade in my immediate vicinity.
