It's Johnny, the media guy, Rogue (a badass solo who eventually becomes queen of the afterlife, also Johnny's ex), Santiago (a nomad who founds Panam's clan if I remembered right)
In both Johnny makes a show in front of Arasaka that turns into a riot as a distraction so they can enter the building and rescue Alt.
Alt meanwhile is being forced to recreate Soulkiller and after completing it they test it on her, but she starts going ham on Arasaka's internal systems, even robbing saburo's accounts.
In the adventure an explosion Johnny's team makes disconnects Alt from the mainframe, trapping her in Arasaka's systems, unable to go back into her body.
In CDPR's version Johnny disconnects her before she can go back into her body, to similar results.
Honestly just having a character who is slightly tech-literate would be enough to save Alt in CDPR's version...
