This game kind of needs a whistle or finger click to help with the stealth aspect of the game, the idea of having to use noise lures,environment or just plain standing in the open to attract enemies towards you is kind of silly.

Would love to see a mechanic introduced where you can simply bind 'whistle' to a certain button on your keyboard or mouse and when holding it down it displays a grey area (similar to that off a diversion lure or flash grenades area of effect marker) in which enemies inside of will be effected. They could even make it a skill allowing players to unlock higher levels with extended range or a higher chance of drawing enemies in close. You could also make it so that holding down said key or button will start the circle at a one or two meter radius and increase slowly until you have the desired loudness or area of effect.

I am sure a similar feature to this has probably been used in games before that allow a stealth style of game play and if it was something as simple as whistling you wouldn't need to add any extra animations to the players character considering more often than not you are not paying attention to your lip movements and some people play with their faces covered anyway.

If this is something that could be added with relative ease I would like to see it done, if not. Well I guess I can always keep throwing diversion lures.
