- Is auto-equipped when matching weapon types occupy Kinetic and Energy slots. Disengages if types don't match. - Restricted to HCs, Sidearms, SMGs due to weapon size. - Fire types (like single-shot HC or burst-fire HC) must match; mode can be set to stagger (alternating shots) or fire-link (simultaneous shots); fire-link has increased recoil based on non-empty mags. Mode can be changed in Settings. - Auto-reload of mags defaultly triggers on the last mag (of the two) to go empty, until which the empty mag will react to trigger-pull like it still has rounds (for purpose of fire pattern). Can be switched to first-empty in Settings. - Re. reloading if both hands occupied, auto-loaders like Lara Croft's (in the video).
