What Happened to Earth in Dead Space? The Open Ending

The Dead Space games never show what finally happened to Earth. In 2514 a large number of Brethren Moons arrive in its orbit, and the last thing the player sees is the moons attacking, after Isaac Clarke and John Carver have heard Necromorphs slaughtering people over the radio. The Black Marker that began the story on Earth is a separate mystery, because its fate is unknown. (Dead Space 3: Awakened; Dead Space Wiki, Black Marker)

What happened to Earth in Dead Space?#

After Isaac and Carver destroy the Tau Volantis Moon in Dead Space 3, the story in Awakened follows them to the CMS Terra Nova and back to Earth. They fit a ShockPoint drive to the ship and arrive, only to hear transmissions of people being killed by Necromorphs, and the Brethren Moons are already there. Then one of the moons rises in front of the Terra Nova and seems to hit it, knocking both men out. The game doesn't make clear whether that last moment is real or another hallucination. (Dead Space 3: Awakened; Dead Space Wiki, Earth; Dead Space Wiki, Dead Space 3: Awakened)

Before that, the colonies had been going dark. After the Titan Station disaster of 2511, the Circle under Jacob Danik began attacking EarthGov's Marker test sites, and by 2514 at least five colonies, including Uxor, had fallen dark over sixteen days. The wiki notes that Earth does not answer Isaac's hails and floats the theory that the Circle seized or destroyed communications equipment. That is the wiki's reading, not something the game states. (Dead Space 3; Dead Space 3: Awakened; Dead Space Wiki, Earth)

Is Earth destroyed in Dead Space?#

Not on screen. The games stop with the moons attacking, and a silent planet plus screaming radio traffic is as far as the evidence goes. The wiki says the silence and the snarling on the radio suggest the people there were being slaughtered, which is a fair inference but still an inference. (Dead Space 3: Awakened; Dead Space Wiki, Earth)

One reading in the wiki's trivia is that the first letters of the Awakened chapters spell R.I.P., which it suggests may mean Isaac, Carver and everyone else did not survive. It's a reading, and nothing in the game confirms it. (Dead Space Wiki, Dead Space 3: Awakened)

What happened to Earth after Dead Space 3?#

Nothing the games show. Dead Space 3 itself ends elsewhere: the Tau Volantis moon crashes into the planet, Ellie Langford sees that her ship can no longer pick up the Marker signal, and she sets a course for Earth. After the credits, Isaac's voice is heard calling for Ellie. (Dead Space 3)

The two endings don't contradict each other. Awakened is set after Dead Space 3's ending, so the hopeful note of Ellie's escape is followed by the news that the other Brethren Moons have woken and were heading for Earth anyway. What became of Ellie after she set course for Earth isn't shown. My read is that Dead Space 3 closes the Tau Volantis story and Awakened opens the Earth one, then stops on a cliffhanger. For Isaac's own fate, see what happened to Isaac Clarke after Dead Space 3. (Dead Space 3; Dead Space 3: Awakened)

What happened to the Black Marker in Dead Space?#

The Black Marker was found in the Chicxulub crater in 2214, and the Sovereign Colonies kept and studied it in secret. Later the danger of the research led the government to move all Marker experiments off Earth, and the wiki says it is unknown exactly what then happened to the Black Marker, though it infers the Marker itself left the planet. (Dead Space Wiki, Black Marker)

At the start of the 24th century the Sovereign Colonies invoked Scenario Five, which aimed to erase and bury the Marker copies and data and the Black Marker itself. The Black Marker's status afterwards became unclear. The wiki's own trivia says it's unknown whether it was destroyed or merely hidden, and it adds that EarthGov clearly can't reach it by the 26th century. (Dead Space 3; Dead Space Wiki, Black Marker)

The Marker Isaac destroys at the end of Dead Space 2 is a different object, a Red Marker copy. If you want that story, read how Isaac destroyed the Marker. (Dead Space 2)

Canon notes#

A 2021 interview with franchise producer Chuck Beaver, reported on the wiki, says the original plan for Dead Space 3 would have led to Isaac bringing the Brethren Moons to Earth, with a Dead Space 4 as a final confrontation there. Beaver said many elements of that plan were reused in Awakened. No Dead Space 4 was ever released (the wiki lists it as a scrapped project), so the Earth ending reads to me as the cut-down version of a story that was meant to continue.
