The Tachyon Egg is the ninth egg in Egg, Inc.

While experimenting with chicken gene therapy, scientists kept recieving premonitions which turned out to usually be true. The cause was found to be a new egg that emitted tachyons, faster-than-light particles.

Time travel was then accomplished with these eggs, but billions were needed for just a few grams. Once countless eggs were layed, a human was sent back to 10,000 BC, cloaked with a quantum cloak to avoid disrupting time.


Tachyon Eggs are black eggs covered in a green pattern with gaps shaped like hexagons. Green particles are emitted by this egg.


  • Tachyons are hypothetical particles that travel faster than light.
