How to Beat Bigfoot in Abiotic Factor
Bigfoot is the hostile entity that "roams the dormitory in Residence Sector," according to abioticfactor.wiki.gg — a brown-furred cousin of the Yeti that swings improvised clubs made from broken Corrupted Bots. Its GATE Compendium entry files it under IS-0255, and the wiki's own combat notes call it "deceptively fast" with "explosive ferocity," but also flag one clean counter: fire, plasma, or "holy" damage. This guide walks through every stat, location detail, weakness, and drop the wiki documents for the fight, plus the trivia the wiki attaches to it.
What Is Bigfoot?
Bigfoot's GATE Compendium codename is IS-0255, filed under the designation "Crucis (AG/CA)." Its containment protocol reads, quoted directly: "IS-0255 is subject to standard megaspecimen containment. Extreme caution must be taken to restrict its access to any objects or items that could be used to fashion tools or rudimentary escape tools, including but not limited to cleaning equipment, dishes, wires and screws, or metallic objects generally." A second line adds that "all personnel undertaking direct study of IS-0255 are required to leave all photographic and recording equipment outside, as the presence of such devices can induce violent agitation."
On stats, the wiki lists 1900 HP on Bigfoot's Head — no separate torso or full-body total is given, so treat 1900 HP as the only documented health figure rather than a combined total. Its Melee Attack does 100 damage, listed as Heavy Blunt type. Its Smash Attack shows 50/125 damage, listed as Explosive type; the wiki doesn't explain what the two numbers in that split represent, so the exact meaning of "50/125" is undocumented beyond the figures themselves.
Where to Find Bigfoot
Location is documented in one line: Bigfoot "roams the dormitory in Residence Sector." No further detail — room layout, whether it's confined to that space, or spawn conditions — is given in the source, so treat anything beyond "dormitory, Residence Sector" as undocumented.
On appearance, the wiki says Bigfoot "is similar in appearance to the Yeti, but with brown fur and a more upright posture." It also notes the weapon: "they wield improvised clubs made from broken Corrupted Bots" — so the club itself is scavenged gear, not a purpose-built weapon.
Combat Tips: How to Beat Bigfoot
The wiki's Combat Tips section is blunt about the difficulty: "The Bigfoot proves itself to be a very tough enemy, deceptively fast and capable striking with explosive ferocity." That's quoted directly because it's the wiki's own framing, not a paraphrase — this isn't a slow tank fight.
The counter is just as specific: "However the Bigfoot is extremely weak to being set alight with fire, plasma or 'holy' damage, which will cause it panic and stop attacking, therefore weapons like the Plasmois Rifle or Flamethrower will make short work of it." No numeric damage bonus is given for that weakness — only that it exists and that it makes Bigfoot panic and stop attacking, which the wiki treats as the practical win condition for the fight. Beyond naming the Plasmois Rifle and Flamethrower, no other weapon is documented as effective, so don't assume other fire-adjacent gear works the same way unless you've confirmed it.
Harvestable Drops and Trivia
The Harvestable Drops table lists four entries. Tech Scrap (x2) and Carbon Plating (x1) are both guaranteed at 100%. Yeti Fur drops in a 2-4 range, listed as "100% of 2 50% of 4" — quoted as written, since the wiki doesn't spell out whether that means a guaranteed 2 with a further chance at 2 more, and guessing at the exact mechanic would be fabricating a rule the source doesn't state. Frozen Essence is the rarest, at 5% for a 0-1 quantity.
Three trivia notes round out the entry: "The Bigfoot uses down-pitched monkey sounds for its vocals." The wiki also connects the recording-equipment agitation rule back to real-world folklore: "The reference to Bigfoot becoming agitated when photographed or recorded is likely a humorous nod to the many years of fuzzy pictures of supposed real life Bigfoot sightings." And in-game lore explains the blur itself — an email the wiki calls the "'Fuzzy' Email notes that the fur of Bigfoot has 'micro-facets, causing it to reflect certain visual wavelengths at obtuse angles,' which gives an explanation for why every photo taken of it is blurry."
Practical tips
- Bring fire, plasma, or "holy" damage — the wiki confirms it causes Bigfoot to "panic and stop attacking," though the exact damage bonus isn't stated.
- The Plasmois Rifle or Flamethrower are the wiki's named picks for making the fight quick.
- Expect it to be "deceptively fast" with explosive melee and smash attacks — don't treat it as a slow tank.
- Look for it in the dormitory, Residence Sector — no further location detail is documented.
- Leave photographic and recording equipment outside the containment area; the GATE protocol states it "can induce violent agitation."
- Tech Scrap and Carbon Plating are guaranteed drops; Yeti Fur scales with the "100% of 2, 50% of 4" rule; Frozen Essence is a rare 5% drop.

Conclusion
Bigfoot (IS-0255) is a 1900 HP fight (the wiki's only documented health figure, listed under Head) in the Residence Sector dormitory, hitting for 100 melee and 50/125 explosive smash damage while being "deceptively fast." The documented counter is fire, plasma, or "holy" damage — enough to make it "panic and stop attacking" — with the Plasmois Rifle and Flamethrower named as the tools that get it done fast. Clear it for guaranteed Tech Scrap and Carbon Plating, a scaling chance at Yeti Fur, and a small shot at Frozen Essence.
