This Simple Feature on Nuke Has Caught The CS:GO Community by Surprise
The blinders can be operated by simply pressing ‘E’ and can be used from both sides, inside and out. Opening the vent gives a player vision to whatever is on the other side, however, it also acts the other way around by giving the player outside information as well. But no noise is made by the vent blinders when opening or closing them, just a friendly tip for some low to mid ranked players.
This feature is not all that useful but the revelation of its inclusion is what has caught the community members by surprise. In high-ranked games or professional tournaments, players simply charge through the vents or play around them, but do not ever fiddle with the blinders. That would most certainly cost them the round or the game, simply because of how aware all high level players are.
