The Oseram Cannon is a massive, high-detail weapon with a rugged, industrial design, featuring a large, cylindrical barrel reinforced with metal bands and a sturdy, angular frame. Its surface is heavily weathered, showing signs of battle damage, with a mix of polished and rough textures. The cannon is primarily metallic with a dark, burnt orange and steel color scheme, accented by glowing blue energy lines that indicate its power source. Distinctive design elements include intricate Oseram engravings along the barrel and a robust, mechanical trigger mechanism.
