So, we're wondering about the wording and the intended meaning on the 2.0 HB ice, such as Heimdall, Ichi, and Vicktor, specifically the ones that have 3 subroutines.

Say I play Early Bird on click 1 and gain back a click for playing it. Can I then click through Heim/Ichi twice, getting rid of all three of the subroutines without having to use any sort of icebreaker? Or is it the case that you cannot break more than 2 routines by clicking?

If you somehow manage to generate an extra click (through Early Bird, All-nighter, Joshua B. etc) then there is no reason you can't use the double-click to break more than once. Just like how with normal Bioroids, you can use the single-click to break single-sub more than once.
