Army of One

Army of One is a Gambit triumph in the Dredgen seal: as an invader, defeat all four opposing Guardians in a single Invasion. The in-game objective tracks "Army of One" medals; three are needed, so you must wipe the enemy team three separate times as an invader.

How to complete

1. Before invading, bank Motes and pick up heavy ammo; the invasion portal gives you True Sight, which makes locating enemies easy.
2. Bring a lethal Super such as Chaos Reach, Golden Gun or Glacial Quake, and a heavy weapon. Guides recommend the Truth rocket launcher; community players also suggest Xenophage, Thunderlord and 450 RPM linear machine guns.
3. Invade when the enemy team is split or low on health, and kill all four before the invasion ends. The kills must all be in one invasion, not spread across several.
