Sin approached the bunker he was dropped off near, assuming his allies had taken up position inside. He banged his heavy shield against the concrete, making a loud metallic clang that would definitely be heard by any inhabitants of the structure. The Mgalekgolo emanated a rumbling noise before remembering the communication device he was recently equipped with. "This is Sinaga Rosu Kinna, I am allied with the Separatist Covenant forces and have been ordered to provide any aid to Separatist and human UNSC forces in the area" The communication device translated into a soft human male voice, rather surprising to hear from hulking hunter over twice as large as most humans. Sin stood near the bunkers entrance as he waited for a response, sensing at least one humanoid life form inside.
