The Inflato-Ray is one of the least shotgun characteristic weapons within the shotgun class. If fires a laser beam that inflates enemies over a small period of time, before the enemy over-inflates and explodes into a gory mess. It uses Charge Capacity and does not run out of ammo, and fires continuously until the trigger is let off or the Charge Capacity runs dry. Like the Thumpgun, the Inflato-Ray will be more effective at longer ranges, but can be effectively used to to stun and kill close-range melee attackers. The exploding target upgrade makes the Inflato-Ray significantly more effective against groups of enemies that are clustered together.
The Inflato-Ray suffers from long recharge times and is useless until the gun recharges enough, and also needs the extra time to recharge longer so the Inflato-Ray can fully inflate enemies for the kill, as simply hitting the enemy for a short period will only stun then and leave them to deflate and recover. The issue with the Inflato-Ray is that the enemy needs to be hit by the beam long enough so they are about to burst, so all the other weapons in the shotgun class are much more suitable for fast paced combat.
