SPEARGUN

The Speargun is an underwater weapon referenced in leaked GTA 6 build material, tied to diving and swimming mechanics rather than land combat. GTA V introduced an underwater speargun alongside its scuba and submarine content, and this leaked reference suggests GTA 6 continues supporting underwater exploration and combat in some form, fitting given how much of Leonida's map is built around coastline, the Keys, and swampland. Full mechanics remain unconfirmed since this comes from leaked material rather than an official trailer.
