Shotgun
From WikiRaider
The Shotgun has been in Tomb Raider from the beginning.
In the first Tomb Raiders there was only one kind of shotgun ammo. Since The Last Revelation the Shotgun had two different kinds of ammo, normal ammo and wideshot ammo. The wideshot ammo is best used against multiple opponents or a bigger one like the Dragonheads in Rome.
In Angel of Darkness the shotgut is the V-Packer.
