NEWS (6 March 2018):

ALPHA 5 is here! The fifth Alpha version features gun turrets, many new items and weapons, and much more.


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).

See the game website for more info and the development blog for details of recent updates, or follow Xenomarine on Twitter


  • Rich, Tactical Turn-based Combat
  • Infinite, randomly generated levels
  • Atmospheric 3D lighting
  • Unique useable items such as scanners, stimpacks and directional forcefields
  • Over 140 unique enemy types (in Alpha)
  • Over 70 learnable skill upgrades
  • Random miniquests
  • Multiple damage types and status effects
  • Crafting (craft items from scrap and upgrade weapons and armor)
  • Hack drones and turrets; deploy traps; use alien tech
  • Intuitive user interface, with mouse-only and keyboard-only support
  • Realistic sci-fi sounds including randomly generated atmosphere sounds


XENOMARINE is currently in development, but is available to download in two different versions.

With the recently released ALPHA 5 the game is nearing completion in terms of mechanics and content. I'd say that with ALPHA 5 the game is about 85% complete.

There is also a free DEMO version, consisting of the first 3 levels of the Alpha, making it a fun, playable minigame.

The Full game is expected to be released in early 2018 on PC, Mac and Linux. Buyers of the Alpha will of course get free access to any further updates, including the full game itself when it is released (NB it is currently planned that the full game will have a higher price than the Alpha).
