Microfusion cell


The standard version of the microfusion cell.

Microfusion cell, bulk


The bulk version carries a smaller charge than the standard version, resulting in a reduction in damage and armor penetration, but less strain on the weapon.

Microfusion cell, max charge


The max charge version causes the maximum possible damage and armor penetration, but at the expense of increased weapon degradation.

Microfusion cell, over charge


The over charge version causes more damage and weapon degradation than the standard version but not as much as the max charge version.

Microfusion cell, optimized


Added in the Gun Runners' Arsenal add-on, the optimized version causes more damage than the standard version and over charge version and weighs less than the other versions, but with slightly increased weapon degradation.
