Broken Destructibles mod gives you an opportunity to remove objects on the map that can be penetrated (walls for example).
On / Off – F10
– hide_mode – allowing you to have the mod activated ONLY when the aim circle is near a penetrable object. By default the option is disabled. To enable, change the hide_mode from 0 to 1 in res_mods\0.9.18\scripts\client\gui\mods\mod_breakable.json
