I was a tiny bit disappointed in the presentation of these in the Forsaken Bounty scenario, since they supposedly factored in to one of the encounters, but there didn't seem to be enough about them.
My PCs just kept their void suits on the whole time. Granted I should have made them pull out a patch or something when they took damage, but I forgot in the heat of battle.
Are void-suits bulky? Can you wear them over armor? Are they expensive? Do they provide armor? What difference does having a void suit give you over a void breather?
