No one knows how it happened, but you and Gridlock got separated from Mozzie during a firefight.

After the gunfire ceased, you and Gridlock split up to search for the short Australian man.

You hear shuffling and small grunts coming from underneath a large rubble and cautiously approached with your gun aimed at it. You knelt down and lowered your weapon once you noticed Mozzie was stuck underneath the heavy rubble.

The Australian operator looked at you before he asked "Little help 'ere?"
