Castlevania: Belmont's Curse Demo Walkthrough

Walkthrough
Quick answer: The demo (live since October 1) is a complete opening chapter you can clear right now — Paris Streets into the Sewers, a boss fight against The Fallen, then a backtrack that unlocks a hidden Cestus. The full-game route expands here at launch on October 15, 2026.
This page is the discovery hub for the playable content: each area links to its Boss, Weapon, Arcana and secret, so you can jump straight to the piece you're stuck on.
Demo walkthrough
Opening — Paris Streets
- Where am I? Rose Belmont's first steps in 1499 Paris (Story).
- What do I need? Nothing yet — this stretch teaches the whip and basic movement.
- What can I miss? Nothing gated yet; it's the tutorial corridor.
- Where do I go next? Down into the Sewers.
Sewers
- Where am I? The sewer network under Paris — the same setting as the The Fallen encounter.
- What do I need? The Vampire Killer whip for traversal, plus your first look at the Mirror of Life (a mirror that restores potions).
- What can I miss? Early secrets and the high-route backtrack that matters after the boss (below).
- Where do I go next? The boss gate at the end of the sewer route.
The Fallen — opening boss
The chapter ends in a fight against The Fallen, the first major boss. He's a brand-new monster terrorizing Paris. See the boss guide for the Holy Cross mechanic and the win strategy.
- What unlocks here? On defeat you gain the Arcane Whip — a grapple + traversal ability mapped to R2.
Post-boss backtrack — the hidden Cestus
This is the secret most players ask about. After The Fallen:
- Backtrack to the Sewer Reservoir, to the area after the first Mirror of Life.
- Use the Arcane Whip to reach an upper grate or platform.
- Grapple upward to trigger a hidden Anchor.
- Ride the Anchor to a hidden room and open the large chest — the Cestus, a close-range fast-combo weapon.
Demo end
- What's currently accessible: the opening chapter, The Fallen fight, the Arcane Whip, and the hidden Cestus.
- What remains locked until full release (October 15): later areas, the remaining bosses, and the full Arcana and Weapon rosters.
What the full guide will add at launch
- Boss order & route — which boss to fight first, and how each victory reshapes your kit via Arcana. The reported sequence is already up on All Bosses in Order; the recommended route lands with the full guide
- Map navigation — save rooms, fast-travel points and key items (Map & Areas)
- Every ending — the reported dialogue choice system branches the finale (Story)
- Collectibles — items and secrets for 100% completion
What's confirmed about the structure
- It's a classic Metroidvania, not a roguelike — save rooms, fast travel and key items (Map & Areas)
- Boss order matters — defeated bosses become Arcana, gating later areas
- Reported multiple endings — dialogue choices change the outcome
