The Twin Sitaray (Sitaroid gemini, dev nickname “sitar-like twins”) is a dark-sea electropredator driven toward shallower water by ecological disruption. It is always born and hunts in pairs, joined by conductive mucus strands; when it attacks, the pair separates at the head to strike from two angles at once.
It emits Collector-Leviathan-like electric pulses (~8 damage/sec for ~3 seconds, plus a ~15 bite) and vocalises with a rising pitch right before attacking — a clear audible tell. It is known to target Electric Geordies and to “play” with metal debris, which means it can damage bases and is extremely aggressive toward Tadpole vehicles.
Counterplay: the rising-pitch call is your cue to brace or break off. Fight near terrain so the pair cannot flank from both sides, and keep vehicles out of its large hunting radius near the Power Plant.
