"What causes almost all life on Earth to suddenly vanish? Explore the five biggest mass extinctions of the past. Then ponder: Could it happen again? Who or what will survive?" ― Information Tab

Life After Apocalypse is a limited time event which mainly focuses on Mass Extinctions. Like the Tech Tree of Life, this one features generators that produce its main currency per second, Species. This is also the first event which the currency's icon changes depending on the player's progress In the event. (DNA Helix, Trilobite, Placoderm, Tetrapod, Archosaur, T. Rex, Homo Sapiens, Cockroach)

The event officially started on September 14th, 2022 at 16:00 UTC and lasted until September 20th, 2022 at 16:00 UTC.



"In all my simulations of life, I detect a surprising pattern of death. I have noted five distinct events in which more than half of Earth species die off forever. What causes almost all life on a planet to suddenly vanish? Could it happen again?"


"Like evolution, extinction never ends. It is a relentless cycle of death followed by new life. Even Earth itself will die. A question remains. Will any Earthlings be strong, sentient, and wise enough to outlive our home world?"

LUCA L.U.C.A. The last universal common ancestor (LUCA) is the earliest microbe from which all modern life descends. Its DNA will pass through a chain of evolving species that survive every extinction. Three billion years later, LUCA's genes are inside us — and every living thing. N/A 40 4
MetazoanSeas Metazoan Seas Metazoans (multicelled animals) multiply and diversify in an evolutionary leap called the Ordovician Radiation. They build the first coral reefs, dense with life. The scattered land masses host only mosslike plants called bryophytes. Ordovician 350 8
Age of Fishes Age of Fishes As life begins to thrive again in the Devonian Period, millions of acres of coral reefs span the seas. This is now a fish-eat-fish world. Big-jawed, heavily armored fish called placoderms take hunting to ferocious levels. Devonian 200,000 2,000
Pangean Life Pangean Life The Gondwana and Euramerica continents crunch into one supercontinent, Pangea. A few tetrapod survivors give rise to a stunning range of vertebrates called synapsids. For the first time, land life is as rich and diverse as ocean life. Permian 60.00M 40,000
Mesozoic Dawn Mesozoic Dawn As a new era begins, Pangea drifts north, and cooling triggers million-year floods, which help life recover. The first flowers bloom. Mammal-like reptiles called therapsids thrive. Archosaurs give rise to reptiles, birds, and — famously — the dinosaurs. Triassic 3.00 E10 5.00 E6
Reign of Dinosaurs Reign of Dinosaurs Thanks to a stable, tropical climate, dinosaurs explode in size and diversity in the Jurassic and peak in the Cretaceous. Reptiles — flying, swimming, walking, crawling — and small mammals also thrive. Cretaceous 3.00 E13 1.60 E9
Age of Mammals Age of Mammals In the current Cenozoic era, the demise of dinosaurs makes way for mammals. Our squirrel sized, nocturnal ancestors evolve into thousands of stunning species, from mastodons and saber-toothed cats to whales and elephants and, eventually, humans.

Ice Age Ice Age! Less carbon dioxide in the air means more of the sun’s heat escapes into space, cooling Earth. The Gondwana supercontinent at the South Pole freezes, causing sea levels to plummet. A multi-million-year ice age begins! 1.00 E7 100

Mega-Volcanoes Mega-Volcanoes In northern Pangea, Earth’s crust slits open, and its molten guts spew out for nearly a million years. The continental lava floodplain, now called the Siberian Traps, grows to an area the size of Europe. 4.50 E10 200
Toxic Ash Toxic Ash More lethal than lava floods are clouds of toxic ash circling the globe. They are extra deadly because of the chemical makeup of northern Pangea’s crust. One of the biggest volcanic eruptions in Earth’s history happens in one of the worst possible places! 2.75 E11 200
Ozone Destroyed Ozone Destroyed Northern Pangea’s crust contains salt from dried-up seas. Burning salt destroys the ozone layer, the atmospheric gases that shield life from the Sun’s ultraviolet (UV) rays. UV rays damage DNA, causing cancers, mutations, illness, and sterilization. 6.00 E11 300
Acid Rain Acid Rain Four billion tons of sulfur erupt into the air. The resulting sulfur dioxide creates acid rain that poisons land and water globally. Bacteria in the ocean generate hydrogen sulfide, which turns the water toxic. 6.00 E12 125

Killer Space Rock! Killer Space Rock! In an instant, the world changes. An asteroid punches a hole in the atmosphere, and the vacuum of space swoops in. Half a second later, it blasts a mantle-deep crater, ejecting crust into orbit. In minutes, a wide swath of life in what is now the Americas is dead. 4.50 E15 300
Shock and Boom Shock and Boom Speeding 20 times faster than a bullet, the asteroid creates shockwaves, air blasts, and a sonic boom that rings the whole planet like a bell. The boom is 500,000 times louder than the Krakatoa eruption of 1883, the loudest sound on record. 3.75 E16 500

Ice Age (Again) Ice Age (Again) Antarctica drifts south and freezes. Sea levels fall, and glaciers flow at both poles. An ice age begins. We're still in this ice age 2.4 million years later. Although polar ice is receding now, we could tip back into a deep freeze. 7.25 E17 200
Anthropocene Anthropocene Anthropocene ("recent humans") describes the period when human activity impacts Earth’s climate, geology, and biology. It spans from at least as far back as the Industrial Revolution (1760) to the present day. 3.00 E18 9,000
Human Impact Human Impact What we’ve done to Earth (so far): Dam or divert most rivers; transform a third of the land; overfish and overhunt; accelerate the extinction of species; and reduce diversity. Only 3% of the biomass of land mammals is wild — the rest is human, livestock, and pets! 9.00 E19 1,500
Extinction Threats Extinction Threats What will trigger Earth's next mass extinction? As in past events, it will likely be a combination of stressors. Our current and future actions can stave off some threats. For unavoidable events, we can only plan for survival. 2.00 E21 700
Climate Tipping Point? Climate Tipping Point? Carbon dioxide is rising at a superfast rate because of burning fossil fuels — gas, oil, and coal. Melting permafrost unleashes methane into the air. These sunlight-trapping gases could trigger a Permian-like scorched Earth, with only the poles as a refuge. 1.25 E22 250
Dead Oceans? Dead Oceans? Seas are warming and acidifying rapidly, killing coral reefs and destabilizing food webs. Oceans could turn into dead zones, as in the Ordovician extinction. Overhunting, loss of habitat, and pollution also threaten global life. 3.00 E22 100

  • There is a small chance that when you buy a lot of generators (like L.U.C.A.), the counter can get corrupted and display the wrong number of units collected (see gallery).
  • When the event ran for the second time, the garden showed the wrong visuals. (Ex: showing the human impact visuals while you have the solar apocalypse)
  • If you stay in the event after it finishes, you can buy the extinct generators but do not produce anything.
