I upgraded my head recently. I installed a Neural Lace 'Blackglass' Net Intrusion 920-40 implant into what I've come to regard as my Explorer Clone: the version of me that has a whole bunch of very expensive implants installed in it, all to make me uncatchable, undetectable and as slippery as a Gallente politician.
The Blackglass implant is remarkable, incredible in its enhancement of my ship's hacking power. It is so powerful that the total combination of ship, modules and implants means it is now virtually impossible to fail even the most difficult of hacks.
Even when this happens:
And even then I still succeeded in hacking the Serpentis data node. But I'm not proud of this. There was no elegance, no style, no precision to this hack.
Sometimes God sends these things to test us.
Don't get complacent out there. You will die. It might even be me that kills you if you happen to be in Syndicate.
