They've adapted the Reaper code. It is different in the sense that they are now "taking" their next step and it not being handed to them. We are also given the impression that the Heretics were also possibly religious towards the Reapers as well as seen on Feros.

I think Thane knew what he was doing in the fight. It was an unknown enemy that could cloak if given the chance, He had to stay close and engaged to prevent losing sight.

I have a problem with Tali taking off her mask and not getting sick. She made a point in both games about how despite it being their homeworld they still need to adapt their immune systems. She even had to drug up just so she wouldn't get sick with Shepard in ME2 and still got the sniffles. Here? Nothing.
