Set the game mode to Horde and without any Mutators. Shoot the generator controlling three light spots. Kryll will begin to appear at three location. Go to one of three locations and look for a sword used by RAAM. When you find it, press X to take it. Note: When you grab the sword you will hear RAAM scream. Do this two more times and a sword should appear next to the sniper rifle just outside of the Kryll location (not where the Kryll are located, because the sword you find there spawns in that location). After you collect that final sword, your character will fall to the ground and a group of Kryll will circle around him. Your character will float, and a Vulcan will appear for everyone in the team.
