Limulidatic Takeover: Horseshoe Crab Invasion!
by DrPilotMOO
Limulidatic Takeover: Horseshoe Crab Invasion! is a Forge mob mod that starts a hostile crab invasion in a running world, aimed at players who want a chaotic horde.
What it does
After five minutes of play in a world, hostile horseshoe crabs begin to spawn five blocks above living entities, and they hunt the nearby creatures and players. Killing a mob causes more horseshoe crabs to appear, with the number scaling to the health of the mob that was killed, so the invasion grows as the fight goes on. The author describes the crabs as ignoring invincibility frames, which means they can keep attacking during the brief window after a hit.
The mod runs on the client and on the server, so both sides need it. It is published for Forge only, across six game versions, with 1.0.0 for 1.20.6 as the latest file. The code is available publicly, but the license is All rights reserved, so the mod is not open source and reuse requires the author's permission. The author released it on 2024-10-13, and the file has not been updated since.
The author notes warn that the mod causes lag and that the content is intentionally unpolished, so it suits players who accept that tradeoff. Compare with the other Forge mob invasions in the catalog to find a gentler or more polished option.
Key features
Timed crab spawns
Horseshoe crabs begin to appear five minutes into a session and spawn just above living entities.
Scaling reinforcements
Each kill adds more horseshoe crabs, with the count tied to the health of the mob that died.
Invincibility frame bypass
The crabs ignore invincibility frames, so they can keep dealing damage during the short recovery window after a hit.
Hostile hunting behavior
The crabs act as hostile hunters that pursue living entities rather than waiting in one place.
