Grenade

Protean Grenades, frequently shortened to simply Grenades, are first acquired when after the weapons vendor in Fyrestone first opens. You can buy them at ammo vendors, find them in chests, or after they are dropped by enemies. Like all ammo types, your grenade capacity can be upgraded by buying the appropriate SDU's from the ammo vendors throughout Pandora.

Grenades can be modified by a wide array of grenade mods which increase their damage and grant various effects and elemental properties. These can range from the classic sticky grenades and proximity mines to the more exotic rain and transfusion grenades.
