Destiny 2 dev thought it would be "impossible" for someone to clear the MMO FPS's new horde mode solo until now: "I'll never underestimate this playerbase again"
Destiny 2's latest big update, Into the Light, launched with a hardcore horde mode called Onslaught that at least one member of the development team thought would be impossible for a solo player to complete. You can probably guess where this is going: somebody has already soloed Onslaught on its highest difficulty.
