Ooh thanks for pointing out the tag, just added that now!
Salvage only triggers when you would definitely lose a probe (it's basically an extra life), so armor's still useful for preventing that from happening.
EDIT: Also, seems like I can die by Proximity even if it triggers on the last required turn, since Salvage triggered before I got the level complete screen.
Thanks for adding the tag! Congrats on being 6th best rated!
Somehow died while armored:
EDIT: Oh, I got double-hit. mmm. Mined and Turreted.
