"Large shells for use with the grenade launcher. Emits a blinding flash and deafening noise upon impact."
Flash Rounds is an item in Resident Evil 5. These are special rounds that can be purchased from the Item Management screen after being found in a chest near one of the moving statues in Chapter 4-1. They function like Flash Grenades; Blinding common enemies and instantly killing the Plaga. Per slot, more can be carried than hand tossed grenades, and they are more precise due to the straight-line nature of the rounds. These rounds are also used by Excella Gionne in "The Mercenaries Reunion".
