Earth Invasion Begins

The galaxy's oldest nightmares woke up, and humanity was the first to hear them scream.

Humanity's first encounter with another space-faring species resulted in the First Contact War, but the Council intervened to achieve peace and welcomed humanity. The first three games center on Commander Shepard, a leading Special Forces soldier in Earth's Systems Alliance space force, the Systems Alliance Navy.

Lore & Background

The source does not describe an event called 'Earth Invasion Begins' or any specific invasion of Earth. The original trilogy depicts a war between the Reapers and the rest of the galaxy in Mass Effect 3, but no details about an invasion of Earth are provided. The First Contact War is mentioned as humanity's first encounter with another species, fought against the turians, not the Reapers or Geth. The source states that the Reapers scour the Milky Way every fifty-thousand years to eliminate all higher forms of life, and that their appearance in the current cycle is being manipulated by forces including Cerberus. However, no specific battle or invasion of Earth is described.

In Their Own Story

The source does not provide a narrative about an invasion of Earth. It states that in Mass Effect 3, the game depicts a war between the Reapers and the rest of the galaxy, but gives no details about specific battles, locations, or characters involved in an Earth invasion. Commander Shepard is the player character who attempts to save the Milky Way galaxy from the Reapers, but the source does not describe any particular event called 'Earth Invasion Begins'.
