The game combines side-scrolling action with stage progression and character switching. Each hero has different movement and attack traits, making certain areas easier with specific characters. Players move through themed worlds, jump across platforms, avoid hazards, defeat enemies, and fight bosses. Progress often depends on choosing the right character for the terrain and enemy layout.

Zeus

The organizer of the mission who gathers the cast and drives the story forward.

Bill Rizer

A Contra character focused on direct firepower and combat efficiency.

Simon Belmont

The Castlevania representative who attacks at medium range with a whip.

Mandara

One of the selectable heroes used for specific exploration and combat situations.

Learn each character’s strengths and switch as needed for narrow passages, jumping sections, and heavy combat. Save stronger offensive characters for boss fights and tough enemy clusters. Take time to read stage patterns, since safer routes often reduce damage and make progression much easier.
