The playing field is the thing you spend
The reactor is a box whose walls are built from tiny cells. Atoms inside speed up under your hand, collide with each other and slam into the wall. Every hit earns energy and cracks a cell; every broken cell makes the chamber bigger. You chew through the reactor from the inside out, layer by layer, until the fuel rod runs dry.
Raids of 3-8 minutes. Fuel burns every second; clearing a layer refuels the rod.
A fusion ladder. Pack atoms together and they merge into heavier ones: protium, deuterium, tritium, helium-3, lithium-7, plasmoid.
A card draft inside every raid. Fill the charge and pick one of three cards; each card rolls common, rare, legendary or mythic.
A talent tree between raids. Four branches, twenty keystone mechanics that switch on new physics: black holes, portals, shockwaves, golden atoms, fuel veins and more.
Eight layers of wall , from lead to materials that do not exist in nature.
The reactor only runs while you are there: no offline income. Your hand is what packs…
