Quickly switch from shooting a sticky bomb from your combat shotgun into a Cacodemon’s mouth to switching to the heavy cannon and using a precision bolt to knock off a Mancubus’s arm cannons. 

  Upgrade details:

•   Switch weapons and weapon mods faster
• A necessity for later game combat
• Keeps the flow of the game intact to make it a more enjoyable experience
