Lex Mortis is an open-world horror game set on a fully explorable island.
The game’s atmosphere is directly affected by the time of day. During the daytime you will study the island and it’s mysteries.
But at night the enemies reveal themselves, and the worst nightmare becomes real!

A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

I watched all six minutes and twenty-two seconds of The Lost Valley’s trailer expecting a jump scare. I’ve come to associate pretty ‘realistic’ natural landscapes with sandbox survival and jump ‘em ups, and appropriately expect cannibals, sharks, and Slender Men. No, not here. It’s simply six minutes of someone wandering down forested paths, wading through streams, and poking around scraps of abandoned civilisation. Curiously, the makers’ last game was one of those pretty world spookfests, Lex Mortis , which seems to be praised for prettiness but curse
