Martin, webcams and the flash drive were part of the old Martin route in the 1.x version of the game. The 2.x version has simplified the process, it appears as if you just annoy him enough times he goes away now, LOL. I actually liked the more convulted route in the previous version of the game but this keeps the NTR antis happy, I guess.the martin character is supposed to show up 2 weeks after the aunt's shower scene giving you time to learn to hack, instead he shows up the next day. So how are you supposed to get spy cams and hack and all that, when there is not enough time.
Not to mention the hacking for money no longer shows up.
