Destruction of Earth

The Destruction of Earth was a major and tragic event that rendered planet Earth uninhabitable.

Lore
When the Citadel was destroyed, the explosion not only killed all life on Earth, but brought the attention of the Titans. When they arrived, they engaged battle with the isolated Combine forces that were on Earth. Realising they were far too powerful, the remaining Combine forces left and abandoned Earth.
