A tool for megabase builders. Science Overload adds 5 infinite researches that require all 7 base science packs plus increasing combinations of planet-specific packs — from Vulcanus alone all the way up to all four planets simultaneously.
These researches have no in-game effects. The point is to give your science production something to chew on indefinitely.
Researches:

Volcanic Vigour — Vulcanus
Galvanic Grit — Vulcanus + Fulgora
Fermenting Fury — Vulcanus + Fulgora + Gleba
Absolute Ambition — all four planets
Arctic Arc — Vulcanus + Fulgora + Aquilo
