Hey Explorers,

The demo of O3: Hollow Descent has been fully tested on Steam Deck and is playable from start to finish.Here’s what you can expect:• Full controller support (no mouse & keyboard required)• Steam Deck button glyphs

• Native 1280×800 resolution (default)

• Stable 55–60 FPS during gameplay

• UI optimized for handheld readability

As a Steam Deck player myself, I’ve been testing the demo directly on Steam Deck to make sure it feels right in handheld mode.

Official verification is still pending, but based on my testing, performance and controls are solid and fully playable.

If you’re playing on Deck, I’d really appreciate your feedback.
