About this game

BECKON OUR EXTINCTION

3242 CE:

We launched MOTHER, a self-replicating megastructure towards the galactic centre.

4,199,245,344,263,242,348,389,893,582,349,373 CE:

MOTHER has consumed 99.99999997% of the Observable Universe.

The remnants of humanity dwell in the remaining space, harvesting and living off MOTHER’s blood.

MOTHER created you to stop them.

BLOOD = SAP

ALTEREDBLOOD+ (AB+) is a fast-paced Movement-FPS about Painting levels in your enemies’ Blood, awakening your weapon’s abilities, and using their unique interactions with Blood to create powerful setups and combinations.

SPLATTER | SOAK | AWAKEN

SPLATTER 

  • Your attacks blast SAP onto surfaces behind enemies. Enemies explode into Gibs, spreading more SAP. Saturate the arena with SAP.

SOAK

  • Stand in their SAP or Bathe in their Gibs to awaken your weapons and abilities.

AWAKEN

  • Escalate the slaughter: when Awakened, your weapons gain powerful effects and unique interactions with SAP.
