Kube requested logic again from me for DejaVu. (I don't know why, but he'll never learn.) 2S is a CP-KOTH hybrid in which teams must capture and hold the points. One point controlled will make the team's timer count down normally while controlling both will make the timer count down twice as fast!
If you'd like to change the time required to win each round, change the tf_logic_koth 'Timer Length' value as well as the counter_time_zz_2s 'Initial Value' and 'Maximum Legal Value'.
Disable the VisGroup WorldBase when copying the logic.
