Gatling Gun (RE2)

The Gatling Gun is a secret weapon found in Resident Evil 2. It has infinite ammunition and has an incredibly fast rate of fire. The player is able to mow down any enemy with ease in only a few seconds. The only draw back is that it takes a moment for the weapon's barrels to spool up and then another few seconds for the turret to begin to fire. This means that you must fight enemies from a distance. To obtain it, beat the second scenario in less than 2 1/2 hours without saving and get an A or B ranking.
