Continuity mistake: Character Alec Trevelyan: In almost all his appearances in the game, Alec is right-handed, holding his weapon in a right-handed position. However, at the end of the level Control, if you manage to sneak in or glitch into the elevator, Trevelyan will be holding his weapon in a left-handed position.
Chosen answer: In normal gameplay, yes, this is the only level where you can dual wield two different weapons.

The question was why is this the only level that two different guns can be held. Not is it the only level where guns can be held?
Thank you. Though it doesn't really matter now. I asked this question like 12 years ago in 2013, when I was still in my early 20s and didn't know anything about game design. I fully understand this now.
