Alien Challenge (China) [Imperfect sound]

Getting Started: Press Enter to add a credit (if in attract mode) and V to start. You control a space marine or mercenary tasked with clearing screens of alien creatures. Move with the d-pad and use the A and B buttons to shoot and jump. The core loop is straightforward: survive waves of enemies, collect power-ups or score items, and advance to the next area. Since this is an unaltered arcade game, there is no save system - progress is lost when you run out of continues. Expect the audio to cut out or sound garbled; the emulation handles the imperfect audio gracefully but it may still affect ambiance. Treat it like a historical curiosity - focus on the gameplay and remember it's a piece of arcade bootleg history.
