Future Era

Main article: Future Era (Civ6)

Note that this era of technology, unlike all other eras, is semi-randomized: all 7 technologies will appear in the game; however, the prerequisites to unlock them (and thus, how the tech tree looks in this era) vary each time.

The exact Science costs of Future Era technologies will also vary based on the exact tech tree structure, with earlier techs costing less than base cost and later techs costing more. The cost is 2200 or 2300 Science, or 2500 Science for Offworld Mission.

Advanced AI	2200 or 2300	Boost through Spy	Drone Air Defense: Anti-Air Defense Strength increased to 130.
Advanced Power Cells		Boost through Spy	Particle Beam Siege Cannon: Ranged attacks against cities and encampments are 100% effective and gain +30 Ranged Strength	Carbon emission from units is reduced by 50%.
Cybernetics		Boost through Spy	Enhanced Mobility: +3 Movement, can perform a Jump action to cross over Mountains terrain
Predictive Systems		Boost through Spy		Offshore Wind Farm
Seasteads		Boost through Spy		Seastead, +1 Diplomatic Victory point
Smart Materials		Boost through Spy	Reinforced Armor Plating: +10 Combat Strength when defending against land and naval units	Exoplanet Expedition
Offworld Mission	2500	Boost through Spy		Lagrange Laser Station, Terrestrial Laser Station
