This trick allows you to use a "7-way Plasma Gun" and is useful in survival mode. Acquire the Pulse Gun (that shoots little green waves). Get these Perks: Angry Reloader, Fastloader, and Stationary Reloader. Do not get the Perk Alternate Weapon, as this will mess things up. After getting the gun and Perks, hold [Reload]. Seven-way constant shots should start spewing from your weapon. Note: Do not get the Perk Alternate Weapon. Remain still if you have Stationary Reloader and the shots will fire faster. Try this with the "Weapon Power-up". Barrel Greaser and Fastshot will make the shots go faster, but not more frequently.
