Cosmic Epsilon (Japan)

In Cosmic Epsilon, players pilot a combat spaceship through a continuously side-scrolling world. Your primary objective is to navigate through stages teeming with alien enemies, dodging projectiles and destroying them with your weaponry.

The gameplay system focuses on fast-paced shooting action. You can collect power-up items to upgrade your weapons, increase movement speed, or gain other special abilities, helping you contend with the increasing number of enemies and diverse attack patterns. Each weapon upgrade makes your ship's firepower more potent, allowing you to clear the screen more effectively.

At the end of each stage, players will face a colossal boss with unique attack patterns and specific weaknesses. To win, you'll need to learn their movements, dodge attacks, and devise suitable strategies to inflict maximum damage. The game is also notable for its relatively impressive parallax scrolling effect for an NES title, which creates a sense of depth in the environment.

Cosmic Epsilon offers a classic shoot 'em up experience, demanding quick reflexes and good resource (power-up) management skills to overcome increasingly difficult challenges.
