Hard Tech Tree

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

Changes

• 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.
