Aphelion/doc/Aphelion/Tiers/Tier 3 - Ion Propulsion and Fusion Power.md

Gameplay Goals: Ion Engines allow space stations to travel between planets without needing to ship up Rocket Fuel, using FE to create propulsion directly, though providing slightly less thrust. To help with this power draw, Fusion Energy also becomes available here, which will be needed for Tier 4 - Astrophage and Interstellar Travel.

Materials: Neodymium (Supermagnets for fusion and ion tech) Tungsten (Heat shielding for inside of fusion reactors, maybe add tungsten carbide? Complexity here can be saved for the modpack) Gasses such as Ammonia, Helium-3, and CO2 from Gas Giant Skimmer

Machines: Fusion Energy Ion Engines Gas Giant Skimmer
