Hard Tech Tree

Pushes back a small number of technologies in the Space Age tech tree. Part of Space Age: Hard Mode.

Repair Pack now requires logistic science.
Nightvision Equipment now requires agricultural science.
Landfill now requires the Agriculture technology.
Logistic System now requires metallurgic, electromagnetic and agricultural science.
Note that logistic bots themselves are not pushed back.
A new technology unlocks active provider chests that requires agricultural science.
Cliff Explosives now require agricultural, electromagnetic and metallurgic science.
Kovarex Enrichment Process/Atomic Bomb now require electromagnetic and agricultural science.
Note that nuclear power itself is not pushed back.
Each infinite research technology requires cryogenic science to research three or more times.
More precisely, if we take the technology Physical projectile damage 7 as an example, it is replaced by levels 7, 8 and 9, with 9 infinite and requiring cryogenic science.
This limits the amount one can tackle pre-Aquilo gameplay difficulties by scaling out of them.
