For PC players it is possible to turn off the beep sound that plays ever second when doing bomb defuse missions.

Unless you repair/reinstall, you won't have to listen to the beep anymore. This is nice when you're spending hours grinding a bomb mission.
I did this for the voice call outs when you enter the character select screen/change character too out of personal preference. There's only so many times I can listen to "Breacher Ready!"
To anyone interested in submitting a run, at least one mod (Wavuvi) is checking for new runs multiple times a week. Remember to jump cancel your shotgun slowdown and turn off ALL skills (including team) for fresh runs!
