Survive 5 escalating duels. Breed with each defeated rival and select your offspring.
BATTLE ROYALE
FFA · 5 AMOEBAS · LARGE PETRI
Free-for-all in an oversized petri dish. Bots fight each other too. Last amoeba standing wins.
SIX GENES IN PLAY (REAL AMOEBA BIOLOGY)
MendelianTOX · cysteine protease — T dominant over t
Inc. Dom.CYT · cytoplasm — FG blends viscosity
PolygenicDPS · emerges from TOX × CYT loci together
MultiallelicACT · actin isoforms — V > F > S > C
CodominanceLEC · cytoplasm pigment — RB shows both
Sex-LinkedOSM · X-linked pellicle density
HOW TO PLAY
Controls
WASD / Arrows to move ·
Space to BLOCK (0.5s shield, 2s cooldown) ·
E to ENGULF (phagocytosis grapple, 6s cooldown).
Auto-attack happens whenever your membrane overlaps an enemy.
Phagocytosis (E)
Real amoebas kill prey by wrapping around them. Press E within close range
to start engulfing the nearest enemy. Hold the wrap for ~1.2 seconds and you deliver
a massive 60% max-HP hit. The target can escape if they sprint outside your reach.
SPECIES (RANDOM EACH SPAWN)
Amoeba proteusGeneralist
Balanced freshwater giant. No specialty — well-rounded for any matchup.
Entamoeba histolyticaToxin DoT
Pathogen. Each hit injects cytolytic toxin — target bleeds 3 HP/s for 5 s, stacks up to 3×.
Naegleria fowleriBurst Speed
"Brain-eater". Fragile but blisteringly fast. Each hit triggers a brief speed burst — hit-and-run specialist.
Chaos carolinenseAoE Crush
Multinucleate giant. Tanky and slow. Each hit also damages nearby enemies for 40% splash.
Acanthamoeba castellaniiSpike Reflect
Spiny acanthopodia. Reflects 30% of incoming damage to the attacker — punishes aggressors.
GENETICS — ALL SIX CONCEPTS
Toxin (TOX) Mendelian
Models the EhCP cysteine protease gene. T (active) is completely
dominant over t (inactive). TT = 1.6× damage,
Tt = 1.2× (dominant phenotype), tt = 0.7×.
Cytoplasm (CYT) Incomplete Dominance
F = fluid sol cytoplasm, G = stiff gel.
The heterozygote FG has truly blended viscosity — neither allele wins.
Controls pseudopod extension rate → attack speed.
DPS Polygenic
Damage-per-second is not one gene. It emerges from two loci:
TOX sets damage per hit, CYT sets hit frequency. Neither alone determines DPS.
Actin Isoform (ACT) Multiallelic
A single locus with four alleles — actin variants with different movement speeds:
V > F > S > C.
The most dominant allele present is expressed.
Cytoplasm Color (LEC) Codominance
Pigment granules in the cytoplasm. R = red granules, B = blue granules.
In RB heterozygotes, both pigment populations are produced simultaneously —
the cell displays both colors as a visible split.
Pellicle Density (OSM) Sex-Linked
The pellicle is the protein-rich surface coat that determines membrane
toughness (max HP). Its gene sits on the X chromosome.
Type I (XX) carries two copies — can be a heterozygous carrier
(XDXd). Type II (XY) is a sex linked trait —
one copy, no carrier state, full expression of whatever allele is present.
