Can you use headsets to talk to friends when playing a co op game in SC2? It is probably a stupid question but I want to confirm my hunch about it.
Yep and multiplayer games like the 2v2s and customs on the same team you can just talk. Which is awesome like how starcraft 2 played it out. You can edit in the options to push to talk or free mode to just say something and its sound sensitive.
Do you mean you press a button and you can talk freely or you push a button type a sentence and the sentence gets converted to a voice the other team players can hear?
