Shatterline

Shatterline is an arena FPS featuring the roguelike co-op Expedition mode and traditional PvP modes including TDM, Conquest, Plant-the-Bomb, and Escort. Choose from Operatives and customize an arsenal of weapons with attachments. Set in the near future, the game follows humanity's struggle against a threat of cosmic proportions. Players take on the roles of the Immunes, people with an extremely rare genetic combination that allows their bodies to resist the alien plague.

The year is 2028, and Earth is slowly being 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 defeated by conventional means. While humanity fears this cosmic plague, some see it as a blessing. The Strafe Witnesses, an army of fanatics, seek to subdue the Crystalline and use its power to advance themselves to the next stage of evolution. Standing between hope and the end of the world is Shellguard, a small group of individuals who are immune to the Crystalline. These few survivors carry a rare genetic combination that grants resistance to the alien taint. Only they can stop the Crystalline, or allow it to change our world forever.
