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.
