а как включить?

Mod's okay. Kind of annoying that the night vision itself is tied to weapon animations but it is what it is. What's more annoying is the spot texture on the sides whenever you enter a narrow corridor or something. It's not game-breaking, but it is noticeable. Maybe instead of importing the night vision texture, you implement the whole thing?

Include the sounds too, or make an individual mod so the user can pick which one they prefer.
