The goal of the game's story is to kill the 1.2 billion Red Communists that invaded Hong Kong. However, it is practically impossible to achieve that goal normally in-game due to Chin having only one hit point, the fact that the score meter will visually loop back to 1000 after reaching 8888 points making it hard to tell what your actual score is (this could be due in part to the number 9 being nonexistent in the game's score counter), and that, hypothetically, if you killed one enemy per second (while also accounting for the extra time it takes to defeat the game's only boss, Tong Shau Ping, multiple times), it would take around 38 years to reach a score of 1.2 billion in one sitting. The only quick way to reach a score of 1.2 billion is to cheat by manually changing the score value in a memory scanner/debugger. Doing this makes the score counter stop properly displaying the score, and causes the continuously looping theme song "I Love Beijing Tiananmen" to stop playing due to that high of a score overloading the game's memory.
