Green Eco (ammo) is used as Lobber ammo. The lobber is the green eco mod. The green mod replaces the dark mod. The lobber drops small green-eco grenades. Jak obtains the Lobber mod in Keira's workshop onboard the Phantom Blade, after finding Light Eco at the Abandoned Research Rig. The Lobber fires a single Green Eco grenade in a forward arc. The grenade remains in place until touched by an enemy - after it is touched, the grenade explodes and deals heavy damage. The Lobber works great against small groups of enemies.
