Understand Atomic Fallout
Useful when…
- Add Radiation damage while also increasing a Shotgun’s magazine capacity.
- Use its lower-rank values to fit capacity needs while investing toward stronger dual bonuses.
Effects and compatibility
At maximum rank, Atomic Fallout grants +60% Radiation and +40% Magazine Capacity. It is a standard Shotgun mod with Madurai polarity and base drain 4.
Rank and capacity choices
It has ranks 0–3: rank 0 gives +15% Radiation and +10% Magazine Capacity, rank 2 gives +45% and +30%, and rank 3 gives +60% and +40%. The listed final step from rank 2 to 3 costs 120 Endo and 5,796 Credits. Lower ranks preserve capacity while still providing both effects; raise it when the added bonuses justify the capacity and fusion cost.
Magazine-focused alternatives
Ammo Stock is listed with +60% Magazine Capacity and has base drain 2; it offers more magazine capacity than Atomic Fallout’s listed +40% but does not list Radiation damage. Burdened Magazine also lists +60% Magazine Capacity, with a -18% Reload Speed penalty, and base drain 6. Flawed Ammo Stock is a Flawed variant with +20% Magazine Capacity. These comparisons help separate capacity from the combined elemental and magazine effect.
Limitations and tradeoffs
- The combined effect uses a standard Shotgun mod slot and has base drain 4.
- Magazine capacity is lower than the +60% listed on Ammo Stock and Burdened Magazine; Burdened Magazine also carries a reload-speed penalty.
Common mistakes to avoid
- Reading +60% Radiation as +60% total weapon damage.
- Overlooking that other compared magazine mods list +60% capacity, or that Burdened Magazine reduces Reload Speed.
