User original request: 我想做一款动作游戏的背景音乐 Xiaowei execution brief: 生成一段30秒的摇滚／金属风动作游戏常规战斗背景音乐，强调持续战斗节奏与自然循环感。 Create a seamless-feeling 30-second instrumental background music cue for regular combat in an action game. Style: hard rock and heavy metal. Drive it with tight distorted electric-guitar riffs, punchy live-style drums, energetic bass, and a clear combat pulse. Keep the intensity strong but sustainable for routine encounters rather than a boss climax. Use a fast, steady tempo, memorable rhythmic hooks, clean transitions, and no vocals. End in a way that can connect naturally back to the opening for looping.
