To be clear, Act 1 includes:
"Need your cojones, son"
"Knock 'em dead"
"The place is an infierno"
What is not clear is whether or not you can simply play these from the quick mission on elevated risk or you need to start a new campaign. Any comments pertaining to this would be appreciated.
EDIT: It seems this must be done in Campaign mode. Credit to Srad Bmith for taking the bullet and trying it in quick mission.
