Low-angle shot across a muddy battlefield under heavy rain. The camera tracks backward as a massive Viking charges forward, axes dragging sparks through wet ground. Lightning flashes — the camera whip-pans as enemies collide with him. The shot becomes chaotic, handheld energy as he spins, cleaves, and roars, each strike sending blood into the rain. The camera circles rapidly as he enters a berserk state — sound muffles except his breathing and heartbeat. He tackles a larger opponent — brutal close combat. Final: he stands alone in the rain, chest heaving, axes dripping. The camera slowly pulls back as thunder rolls.
