I think questions about equipping Garrett were superceded by Dave's further exploration on the subject. Certainly as far as upgrades are concerned (which lockpicks count as)

Stuff about lockpicks etc are (http://www.ttlg.com/forums/showthread.php?t=91960) here, and a better version of inventory creation was actually still stuck in the Deadly Betatesting forum... I've dragged it out and stuck it (http://www.ttlg.com/forums/showthread.php?t=94175) here

I'm just realising how much of the actual writing stuff down was done by Dave :D

Mind you, a whole lot of the Figuring Stuff Out was done by Dave, too. I was primarily concerned with trying to Break Things.

We are currently working on a permanent resource for this stuff, hopefully a wiki format so everyone can contribute as things are figured out. So keep eyes open for that.
