I took two of those with me. One I used right away to try and find the damn exit, the other I saved for later, and even after I spent the drones I held onto it so I could scanalyze and fabricate (which I got to do once!). My first time using drones. Also the first game I got to use a guided weapon (an EMP grenade launcher of some sort).
Ended up with a high score of 8240, having died on -4. I'd been having a big problem finding terminals (of any kind!) for four or five floors, so I was pretty well murdered almost as soon as I entered a floor (-4 lasted 318 turns). -7 I managed to luck out on and find an exit quick (-5 went on for 1315 total turns and I found almost nothing of value).
