The .50 BFG is a Special Forces sniper rifle sold at Wizard Island from Trust level 2. It hits harder than almost anything in the game and holds 10 rounds. Bring it for Reachers, Ragers and anything you want dead in one shot.
It shows up in the Wizard Island gun merchant's stock once your Trust there hits level 2. That puts it in the back half of the game.
It is built for big single targets: Reachers, Ragers, Breakers and armored humans at range. Penetration is high, so one shot can pass through lined-up enemies. Ammo is pricey, so do not waste it on Swarmers.
The Talon 7 hits hard too but holds only 5 rounds, or 7 upgraded. The SSR fires faster with less punch per shot. The BFG sits between them and is the best all-round pick for big game.
