Undertale

Players explore the underground from a top-down perspective, moving through towns, dungeons, and scripted events to advance the story. Battles use a turn-based command system where you can attack, act, use items, or choose mercy; during enemy turns, a heart-shaped soul must dodge bullet-hell style attacks. Many encounters can be resolved peacefully through dialogue or specific actions, and routes and endings shift according to the player's choices.

Frisk

The silent human protagonist controlled by the player after falling into the underground.

Toriel

A kind monster who guides and protects the protagonist in the Ruins.

Sans

A laid-back skeleton with a joking manner and important story knowledge.

Papyrus

An energetic, earnest skeleton who wants to join the Royal Guard.

Undyne

A fiercely determined fish-like warrior who aggressively pursues the protagonist.

Alphys

The nervous royal scientist involved in key events.

Asgore

The king of the underground and a central figure in the story.

Flowey

A strange flower character known for interfering with the player's choices and the narrative.

Learn enemy attack patterns before committing to offense or mercy choices. Many common encounters can be cleared without fighting by using dialogue, compliments, waiting, or meeting specific conditions, and avoiding unnecessary battles has a major effect on the route and ending. During combat, pay close attention to attack cues and keep movement controlled, especially against multi-phase patterns. Save often so you can revisit areas and experiment with different choices.

Tips and tricks

• Try different dialogue and mercy options; many enemies have non-combat solutions.
• Read the enemy's attack description before deciding your action each turn.
• Save before entering new areas so you can handle unexpected tough fights.
