How to Take Vent to Open Door for Greenway (High Ground) in 007 First Light

A 007 First Light guide explains how to use the Laser Strap and a vent route to bypass Greenway’s locked door.

Players reach the executive 2nd floor vent at Webb Industries, drop into the east wing area, and take out a guard.

After that, they hack the door controller so Greenway can move forward in the Knightfall chapter.

The route is important for progressing the mission and completing the High Ground challenge.
