Enter the Dark World in Deltarune

The story begins with Kris, a quiet human student living in a town populated by monsters. One day, Kris and the rebellious classmate Susie accidentally discover a hidden portal leading to a mysterious dimension called the Dark World.

Inside this strange realm, they meet Ralsei, a kind-hearted prince who reveals an ancient prophecy. According to the legend, three heroes must work together to seal dangerous Dark Fountains that threaten the balance between Light and Dark.

If these fountains continue to spread, the world may face a catastrophic event known as The Roaring, a disaster that could consume both realms.

How to Play Deltarune Online Free

Deltarune Online combines classic RPG exploration with fast bullet-dodging combat. The basic gameplay loop involves exploring areas, interacting with characters, and fighting enemies using a turn-based battle system.

Fight or Pacify Enemies

When you encounter enemies, the game switches to a battle screen where your team must decide how to respond. Each character in your party has different abilities.

• Kris can ACT to interact with enemies and attempt peaceful solutions.
• Susie focuses on powerful physical attacks.
• Ralsei provides healing and support magic.

Instead of defeating enemies, you can often calm or spare them by choosing the correct ACT commands.

Dodge Enemy Attacks

During the enemy's turn, you control a small red heart representing your soul. Move it around the battle box to avoid incoming attacks and projectiles. Surviving these attack patterns is essential for continuing the fight.

Use TP for Special Skills

Dodging attacks builds TP (Tension Points). This energy can be spent on special moves, healing spells, and powerful team abilities that help you survive difficult battles.
