Reaper Destruction OTA
In the evening, after one of the Reapers had been destroyed by the ground forces, the second Reaper initiated a beam into space. The Normandy came screeching in and Shepard disembarked, rushing for the beam.
Thirty minutes after she disappeared into it, the Reaper suddenly launched towards space. It exploded in the air, and the explosions of dozens of other Reapers were visible from the ground.
