Big worm

Big worm is a military building that serves as a large turret-style hostile spawner used by the native creatures to defend bases; it functions as a long-range, high-damage offensive emplacement that targets player forces and structures, dealing heavy physical/acid damage over an extended range compared to smaller worm variants. Big worm is encountered as a static defensive installation in enemy bases and nests, scaled to threat level, and is part of the game's enemy defensive hierarchy alongside smaller and medium worm types, presenting a significant hazard to approaching players and vehicles.
