"Well, let's see what we can see," Seren muttered to himself, seating himself in front of the sensor controls and setting to work. Times like this, he was quite thankful for the range of skills he'd picked up during his military career, and that operating remote sensors was one of them. Between that, his skills of observation, and the natural paranoia of a frontline soldier, he hoped to find any difficulties his employer's agents had missed, preferably before he ran into them in person.

The Turian had a marked advantage, having his weapon out and trained on the general direction of the corridor by the time the Batarian showed his face.

The gunshots rang out particularly loud in the confined space, the rifle letting off a short burst of four shots.
