72 Levels

Six chapters. First Light to Vacuum Decay.

9 Atom Types

Each one splits, absorbs, or detonates differently.

Chain Reactions

Reflector walls. Gravity wells. Neutron flux zones.

7 Yield Tiers

Tactical to Vacuum Decay. Bad angles cost everything.

Pay Once

No ads. No timers. No tricks.
