Deltarune Chapter 5 Adds Three Distinct Endings Including a Short, Persistent Weird Route

Overview

• Coverage this week has confirmed Chapter 5 offers three major outcomes: a Normal ending that advances the main story, a collectible-gated Secret Boss ending, and a carryover-dependent Weird Route ending.
• The Weird Route must be initiated across earlier chapters by specific actions with Noelle including freezing enemies, pressuring dialogue choices, and equipping the Thorn Ring.
• The Weird Route’s Chapter 5 finale is a short lake sequence in which repeatedly selecting Proceed produces a CRT-style “Insert Chapter 7 Side B” screen and creates a persistent "_b" save file, while choosing Stop bails back toward the normal path but leaves corrupted dialogue motifs.
• The Secret Boss path requires collecting at least 10 Pink Coins, buying the Mysterious Key, and opening a hidden pink door to fight Mad Mew Mew, a high-difficulty encounter that rewards the Shadow Crystal.
• Players and journalists are now testing how the Weird Route’s special save data affects access to future chapters and interlinked rewards, and fans worry that the route could block optional content or change long-term progression.
