Fortnite's 4.5 update is out now, adding new weapons to both the Battle Royale and Save The World modes. Overall, it's fans of the Save The World mode who stand to gain the most here: that mode is getting a stink bomb, a new Freedom Herald Pistol, and new Stars and Stripes Heroes (pictured above) to celebrate Independence Day in the United States.

The Stink Bomb "unleashes a cloud that damages enemies over time", while the new Herald Pistol – which is available on the Weekly Store – "launches firecrackers that bounce off walls, and will knockback and damage enemies in a small radius when they explode". Also available in the Weekly Store is the Lynx Assault Rifle, a "slow firing burst assault rifle with above average headshot damage and excellent stability".
