Benefits (How this will benefit the server and game as a whole): Stops breaches from throwing a grenade down a ladder and also from marines shooting along the lower engineering hallway. (Which are normally accidental anyway)
Details (Description of how you think this would work, the benefits, etc): Pretty much the summary.
Implementation (Optional, if you have an idea how to implement it): Mapping.
Picture for reference:
White lines represent bullet paths from the engineering hallway.
Red circle represents ladder grenade explosion.
Some of the windows have been filled with walls due to a breach that happened.
