So how deep have people gotten? This was my deepest so far:

Circled in red was a big impediment to getting further :P
Note that I also had 4 health vials and 4 mega health vials.
Alas.
Was still great fun :)
(I uploaded to the wiki to avoid nda breaking things, sorry to pollute things if that is messy.)
My team tonight made it to the bridge of Firestorm Citadel.
We were all "Woo, this is gonna be awesome!" and then we caught fire and died. It was still awesome.
I think that's depth 23?
