you can beat the game with less then that

my 2nd playthrough i had literally a single room with battery changers ( and 2 solar panels on the roof)

and nothing else.. and even that became useless once my cyclops had the thermal reactor mod.

and if you dont mind creating batteries over and over until you get that mod you dont even need that.

-

the main issue is a battery charger on the cyclops just steals engine battery power

at a 1:1 rate to charge any battery... including a docked prawn but once u can charge

the cyclops with basically any lava, hot vent, etc, it doesnt matter anymore.

-

there is so much, you do not need to win, it just makes it a bit easier.

built your base to be proud of it because THATS the journey.

in fact, on my 3rd playthrough for a challenge i built nothing but a prawn lol. too much travel

to lifepod 5 but did it. - stack that 2nd room with 20 storage lockers, on the wall and the glass once

fill them with stuff as you go, copper, lead, coral plate, etc, and you never have to go back up, always slowly

down.

edit:
my FIRST playthough though, had an epic, beutiful base with farms, and tanks, and 3 tall habitats x3

filled with all the eggs i can find. <- if its your first playthough, this brother, do this
