Prime 5★ Gas Refining is a single-level Galaxy research for the endgame economy: every 5★ Gas refine returns one extra batch. It unlocks at R&D Department 53 and its cost includes 370 Rodinium Particles, so it is priced for the players it serves.
What Prime 5★ Gas Refining does
At the 5★ tier, refined gas is a standing bottleneck for late research and components. A permanent +1 per refine effectively raises your 5★ Gas refinery output for the rest of the game, which is why prime projects like this are treated as milestones rather than line items.
