In the Xenotower mission there is the Xenovirus zone. Is this zone starting 16 inches at your table edge into the middle or at the Xenotower towards your deployment zone (the story for the mission seems to indicate that)?
Took me a bloody while to find this mission. It's in the Halloween Special 2018 for those wondering. Third mission in since the PDF doesn't have an index. It doesn't actually say, but it makes sense that it emanates from the tower, making this mission an inverted Biotechvore.
'There is an area 16 inches deep that is infested by a Xenovirus, in each half of the table, including the Deployment Zones.' 'At the start of the second and third Game Rounds, before the first Player Turn begins, the Xenovirus Areas each expand by 2 inches.' The two areas start at back of the Deployment Zones, just like Biotechvore, and they both advance in towards the tower as the game goes on, leaving an 8" strip in the middle that's clear. I don't know why they got left off the map.
