Hiding Spot Marker
Aren't used in any of CroTeam's levels. Doesn't seem to have functionality, yet. Perhaps we'll see some in later Beta releases.
It's idea is simple place them, at places where you think ,that the player might decide to try and hide.Like if you have a big and wide column, every player would go and hide behind it. Simple place one of these there, and if the enemies have it in their behavior, they'll go check it out, once they loose sight of the player .What a surprise he'll get.
Because the spot isn't a single point, you can define a range , for the spot, by expanding the "Hiding Spot Params".
Note: Because I can't get any test results, I'm only guessing here.
