I played comp. on underground.
Enemy team destroyed 1 bombsite and then they planted on the second to run overtime, we defused the bomb after 15 sec so in next round we had 15:15 to complete all objectives.
The funny thing is, when we destroyed 1 objective in second round, we have got time extension to 16 minutes from 12 minutes. Stopwatch is now Objective with 2 rounds?
