Engine and modding

Who is making Frostrail?
Yes: many FakeFish developers who worked on Barotrauma are on Frostrail, along with new talent hired for this project. FakeFish is based in Turku, Finland; it was founded in 2014 and the publisher’s press kit describes an independent studio of about 30 people. A Gamescom founder interview said around 15 people were working on Frostrail at that time. Shiro Unlimited, a publishing label of Shiro Games, is the publisher. Support mail listed on Steam is support@shirogames.com.
