Well, just had another death, though this one happened after what seemed like 4 or 5 lame duck situations I recovered from, so at least that part of the game's design finally worked out in my favour.
Also, I found Zion. I've no clue what it's for other than advanced tutorials. some buddies, and some interesting gear, but it was neat. I can't remember if data miner is on -7 or -6, though, since I've found them before but I don't recall exactly where. Seems like grabbing gear from behind closed doors, or maybe just going into Zion, or maybe the Imprinter (I got a bonus for that), gets the caves full of MAIN.C's goons, since I kept having to fight waves of them just to proceed. Certainly made Signal Interpreters my favourite item.
