What is Battle with Undyne!

Prepare for a fierce one-on-one clash with Undyne, a warrior who never backs down. Her spear-throwing fury will test your reflexes and your resolve.

How to Play

Move your hero to sidestep the spears that Undyne hurls, then dash in to attack when you spot an opening. Time your strikes carefully—rushing in too early will leave you wide open.

Tips for Playing

  • Watch Undyne's attack patterns for a moment before moving; she often telegraphs where the spears will land.
  • Use short, controlled movements instead of running wildly to stay clear of the barrage.
  • Only go on the offensive right after a dodge; that's when she usually resets her stance.
  • Keep your eyes on the center of the screen—it helps you react faster to incoming projectiles.
  • Stay patient; it's better to miss a counterattack window than to take a hit.
