Ok Your in luck. Im an experienced lag switcher

The thing is in uncharted, Its better to lagswitch in survival matches while your host becuase it freezes the enemies in place on your friends connection.
I know you can hold the lagswitch on for atleast 2 seconds in death match, You can melee some people, dont leave it on for to long because... well youl be locked.
