The lights on the magazines' rear and sides are ammunition level indicators, going dark from the top as the Stilettos fire. However the lights on both Stilettos go off at the same time, despite the guns firing consecutively rather than concurrently.
Using black energy in the Smoke Palette or very dark energy colors will make it impossible or difficult to note the lights on the Akstiletto.
Despite the Tenno throwing both guns to their sides during a reload, the Akstiletto will never drop the magazines and they will always be connected to the model.
This is the second dual-wield sidearm that currently does not have a single counterpart (being preceded by the Twin Gremlins).
Like the preceding Vipers, the Stilettos make a distinctive sound when their trigger is released.
Holding a datamass with this weapon and reloading will cause the datamass to spin as if it were the other gun.
