Alien Challenge
异形挑战
Alien Challenge is an action arcade game developed by IGS and released in 1994. Players control a character fighting against alien enemies across multiple stages. The game features fast-paced combat mechanics with standard arcade controls using a joystick and buttons for movement and attacks. Enemies spawn in waves, and players must defeat them to progress through each level. The game includes progressively challenging enemy patterns and boss encounters at the end of stages. Power-ups appear throughout levels to enhance the player's weapons and abilities, providing temporary advantages during combat encounters.
