The Jötunn is a powerful fusion rifle with a distinctive, bulky design, featuring a large, rectangular body with rounded edges and a prominent central barrel. Its surface is a mix of smooth, metallic panels and textured, heat-resistant materials, with a color scheme dominated by dark blacks and grays, accented by glowing orange energy lines that pulse with power. The weapon's most notable feature is its ornate, Norse-inspired engravings along the sides, suggesting its mythical origins and immense power.
