Sci-fi psychological thriller Fort Solis puts players in the shoes of Jack Leary and Jessica Appleton, a pair of engineers on the planet Mars investigating a distress signal from a nearby mining outpost. The linear, narrative-focussed gameplay will mean that players have plenty of time to explore the abandoned base, gathering clues and insights the further they delve into it. For players seeking to attain 100% completion, they will have to unlock the Terra Tour Guide achievement.
In order to unlock this achievement, players must collect all the Posters, Emails, Audio Logs and Banners which are hidden throughout the station. While players will encounter many of these naturally as they progress through the main story, there are some missable items and even entire buildings that players will need to divert to.
