The sentry breaker which will be splashed in most faction, if the runner is looking for an efficient sentry breaker.
While it compare to Bukhgalter in term of efficiency, it is a bit better if you run more than one sentry and a bit worse if you run only one sentry (but sometime equivalent, both breaking Anansi for 5).
Where this breaker is great is the influence cost. For such an efficient breaker, 2 influences is cheap. You will almost always install it for 3, unless you are really push into a corner.
The quote is the translation of french opera of Bizet "Carmen". I encourage you to listen to the epic music from that opera, it is inspiring.
But for my taste, I think the art is a bit vague, while still being evocative of the eponymous opera character.
This breaker was much needed, letting runners have a chance to break sentries effiently without sacrificing a lot of influence.
