The Gastro Gun was a weapon used by Crypto in Destroy All Humans! 2. The weapon fired a HoloPox Unit which had a hologram of Gastro, the Furon Mothership's Janitor. Gastro, along with Orthopox, downloaded his conscience in a HoloPox Unit when the Mothership was blown up. Holding down the fire button lobbed a Gastro Pod further away. Gastro then deployed and vaporized enemies.
