Contra: The War of the Worlds is a single-player action, casual, platformer, arcade, and shooter game in which players control a soldier fighting against alien invaders. It features fast-paced combat, platforming challenges, and shooting mechanics typical of classic arcade titles. In this game, set in the year 2641, Zergs from SX Star have launched an attack on Earth and established a military base on the moon, prompting the government to send a lone soldier to eliminate the threat and defend humanity. It stands out with gameplay elements inspired by Contra III: The Alien Wars, including a health bar, low gravity zones, autoscrolling levels, and a completely new plot and setting, offering a nostalgic yet fresh experience for fans of the series.
