Update R74

It's time for a monthly update, Shatterliners!

Here's what it has brought.



Shatterline is a free-to-play online first-person shooter, set in the near future, where humanity faces a threat of cosmic proportions. Players take on the roles of the Immunes – bearers of an extremely rare genetic combination that allows their bodies to resist the alien plague.

The game features narrative-driven cooperative multiplayer, as well as an array of team-based Versus modes. Whether you prefer PvE or PvP, Shatterline has plenty of both to offer – and meta-game systems encourage players to explore.


Shatterline is a live service. In this game, the developers host the official Discord channel and play together with the community on a regular basis. You can help improve Shatterline, or even shape the direction of its evolution with your feedback. Hop on!


Shatterline features eight unique playable characters. Aside from their specific abilities and perks, all characters have access to an armory of 25 upgradable and customizable weapons. Both characters and weapons gain experience and unlock new features over time.

Weapons aren’t hard locked to characters – any Operative can equip any weapon. Operatives can perform various roles on the battlefield, and combinations of abilities and loadouts allow for creating your own unique playstyle.


The year is 2028. The Earth is being slowly overtaken by the Crystalline – a gigantic interstellar super-organism that devours planets and transforms living species in its own image. This enemy cannot be bargained with, or fought with conventional means.

While humanity fears the cosmic plague, there are some who see it as a blessing. The Strafe Witnesses – an army of fanatics, – aim to subdue the Crystalline, and use it to uplift themselves to the next stage of evolution.

Between hope and the end of the world stands Shellguard – a small company of individuals immune to the Crystalline. These lucky few are involuntary carriers a rare genetic combination that provides resistance to the alien taint. Only they can stop the Crystalline – or allow it to change our world forever.
