NEWS (21 August 2023)

Fourfold Games has just a new title, Relic Space: a turn-based, roguelike, space RPG in which you play an elite starship pilot.


XENOMARINE is a dark, atmospheric, sci-fi/horror themed roguelike in which you play a space marine exploring an alien-infested space station. Starting out with little more than a crowbar, you will fight to survive against over 120 increasingly powerful alien species, as you progress as far as you can through infinite randomly generated levels.

With no starting classes, develop your character entirely by means of in-game choices: choose between over 70 skill levels as you gain experience from combat, and create a unique build each time you play by finding and choosing between hundreds of unique usable items and individually upgradable weapons and armor.

WARNING: This game is hard! Expect to die soon and often when first starting out, and in the default 'roguelike' game mode death is permanent - meaning you will have to start again from level 1. But don’t worry: each playthrough will be different because so many parts of the game are randomly generated (in a way that’s carefully fine-tuned for balance).
