Beefy Bioroid ice like Wotan would be a very effective combo with this card, at strength of 10 and four subroutines, which unlike other Bioroids can't be broken. (Yes the first subroutine can be bypassed by loosing two clicks, but letting a fire and unloading it's payload means that the is NOT being broken). So unless the runner poinies up resources and actually uses abilities &/or ice breakers to actually break the subroutines, Wotan backed up by Bioroid Efficiency Research will likely remain rezzed and doing it's business for the rest of the game saving the corp the 14 install cost.
Blue Sun: Powering the Future can turn Bioroid Efficiency Research and expensive ice into a nifty financial boon many other combos would have difficulty matching. Imagine collecting 15 from 1 Janus 1.0 card installing it three times for a whopping 45 in a single game!
Can open up flat-line kill opportunities
Huge savings can make prohibitively expensive ICE useful
Ice is only rezzed on corps turn, no element of surprise
Without element of surprise, runner may actually be encouraged to run where before there was hesitancy
Ice is vulnerable to being trashed
Limited only to Bioroid ice
Yeah, it's useful. But it's limited probably to HB or perhaps a Blue Sun: Powering the Future Weyland deck.
