The only guns available when we begin the game. They have unlimited ammo. These are Lara's favourites. Not that powerful, though.
Shotgun
More powerful than the pair of Magnums but reloads much slower. Advised to keep it reserved since we won't find many ammo. Great weapon against enemies staying in a short distance.
Magnums
They have higher firepower than the basic pair of Pistols but with limited ammo. Useful against anyone, distance doesn't matter. Probably the most effective weapon.
Uzis
They are rapid but use an awfully lot of ammo (well, obviously). Advised against tough enemies like mutants.
