The hidden demo Cestus is documented
Hobby Consolas reports a hidden Cestus chest in the demo. Q-Gin also reports the discovery, drawing on a player find. These accounts corroborate the item discovery, but the research notes that they do not provide two independent route tests.
That is enough to identify a reported demo acquisition. It is not enough to certify every turn, checkpoint, or prerequisite in a location guide. This page keeps the demo context attached to the find.
Equipment discovery is part of exploration
KONAMI’s overview links equipment acquisition with exploration. This explains why weapon-location questions belong to the exploration side of the game. The publisher material does not supply a complete location catalog in the retained file.
Do not infer a specific reward from a general exploration description. A secret route and the equipment at its end need to be documented together. The guide therefore excludes assumed item coordinates and checkpoint names.

Weapon behavior does not verify its location
PlayStation Blog’s hands-on report independently documents Cestus behavior. That supports the identity of the weapon and its combat role. It is a different claim from proving the exact path to its demo chest.
Combining a weapon description with a discovery report improves context but does not fill route gaps. The research explicitly keeps the reported route outside a verified full-game catalog. This distinction avoids making a played-preview observation do more than it actually supports.
What an exact location entry would need
The source file calls for an acquisition entry with region, checkpoint, prerequisite, reward, and a screenshot. Those details would make an exact route reviewable. They are not all verified in the retained material.
This guide therefore does not provide a step sequence assembled from incomplete reports. It also avoids assigning every weapon family to a guessed area. The documented demo Cestus discovery remains separate from a complete retail route list.
Where to go next
For the Cestus discovery specifically, the secret-weapon page explains the demo report’s scope. For how weapon families differ, the weapons page covers the supported combat comparison. Neither should be confused with a full acquisition atlas.
The direct location answer is limited to a corroborated demo find and the confirmed exploration connection. Exact full-game paths remain outside the verified research. This page preserves that distinction instead of inventing locations to satisfy the keyword.
Sources and research date
This article uses the material retained in the October 13, 2026 research. Official descriptions, developer statements, and hands-on observations are identified in the section references. Details are scoped to those sources and are not a claim of independently completed retail testing.
