Update 2: They have further clarified, again, that it really will be a day-1 release and the person previously sending their messages got confused:
@thenaughtysquid Sarah is confusing beta Linux with launch Linux. Linux is available Day 1 on Steam on Feb 27. Private beta Linux is soon.— River City Ransom (@rivercityransom) February 14, 2017
They have now also put out a Kickstarter update to confirm this.
Update: And again, they seem to backtrack:
It doesn't seem like they really know.
A few days ago I wrote about 'River City Ransom: Underground' [Steam] not getting day-1 Linux support, but it seems it will and the developer had their wires crossed somewhere.
The developer sent a Tweet to me directly early this morning to clear it up:
@thenaughtysquid sorry for confusion; launching PC/Mac/Linux Day 1. Cross-platform play.— River City Ransom (@rivercityransom) February 13, 2017
Great news, looking forward to testing it out!
