Yell

Yell is an option in Completing the Mission during the mid-boss fight in the "Jewel Baron" ending.

After Henry Stickmin has stolen the Norwegian Emerald from the vault of the Toppat Orbital Station, he is caught escaping with his loot in the Orion Lounge by the Right Hand Man and Wilhelm Krieghaus. If Henry uses Yell, he screams so loud it ends up breaching the wall of the lounge, sending all three men into space. Henry is able to save himself by stealing the hat of the Right Hand Man, which contains an oxygen mask.

 * This option references the Unrelenting force shout (Fus Ro DAH!) from Skyrim.
