to level with, as in missions? ballista. load lockpick if you like.. i myself never did and it worked out ok. ive been a proponent of grinding with hacker since day one =D
youll need to go heavy on the resist cuz even tho hacker kills multiple npcs faster than working thru them one at a time with some interlock build or another.. its weaker so youll have to protect yourself. during pvp/rp an operative build is fine but when you just wanna get things done as quick as possible, interlock is for jackasses that think theyre neo and wanna make a movie every time they kill an npc. i dont understand why ppl grind with MA and such. that must take forever.. haha suckers.
hacker ftw.
