im pretty sure what aileron is goona tell you is this (this is all he has told anyone, and sabotaging still fails , so we are all in the dark on this one) 1. you need a 'recon' of the person you want to sab 2. send 1 spy 3. select an apporpriate number of items (1-infinity) ---- now dont ask me how a sentry of 500mill can stop my spy at 4bill.. really i think the whole system is !@#$%^&*
