NEWS (22 May 2017):

ALPHA LAUNCH APPROACHING1 The first Alpha version of Xenomarine is now very close to release: check back soon and be among the first players to experience 15 randomly generated levels and a load of new weapons, items and enemy types.


XENOMARINE is a sci-fi-horror themed roguelike in which you play a space marine exploring a dark alien-infested space station. You start out with nothing but a crowbar, a torch running low on battery and some battered armor...and high hopes of finding some powerful alien tech!

(Just in case you don't know what a roguelike is, think: top-down, turn-based rpg with randomly generated levels that are different each time you play. Oh yea, and when you die, you die - no saved games!)

XENOMARINE is currently in development, but is available to download for free in a fully playable Demo (pre-alpha) version below. This Demo is being updated with new features regularly, but I try to make sure each release is a fun, playable minigame: reaching the end of level 3 should be quite a challenge!

The Alpha is expected to be released in mid-2017. The full game will be released first on PC, Mac and Linux, followed by iPad and tablet versions

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