cl_clutch_mode <true|false>
If true, mutes your teammates' voice chat, radio calls and other distracting in-game sounds so you can focus on enemy footsteps and gunfire during a clutch. Stays active until the end of the round or until you die, then turns itself off automatically.
Examples
cl_clutch_mode true - Mutes teammate voice and radio for the rest of the round.
cl_clutch_mode false - Normal audio (default).
true and false can also be written as 1 and 0.
