Underveil

About the Game

Build your cards. Shape your board. Find what you seek at the bottom of the abyss.

Roguelike Deckbuilder × Spatial Strategy × Card Fusion

「Underveil」is a roguelike deckbuilding game that goes beyond simply collecting cards. Fuse, rotate, and place your cards, expand the board itself, and build your own unique combat strategy!

In Underveil, you can fuse two cards to create a new one.

Rotate, overlap, and combine cards with different shapes and effects.

The fused effects can lead to new synergies and strategies.

What matters is not what you get, but how you combine it.

In Underveil, there is no Energy cost. Instead, what limits you is the space on your board.

Think carefully about where to place your cards, how to rotate them, and what to overlap them with.

It's not about how many cards you play,

but how you use the space you're given. That is what determines the battle.

You begin with a small 3×4 board.

At Sanctums, expand your board and engrave effects onto new cells to create a board of your own.

As your board grows, you can place more cards and create new combinations and strategies.

Engrave your board with various effects that grant Strength and Agility, draw cards, or remove them.

Choose what kind of cells to create and where to place each effect.

Not only your cards, but the board itself becomes part of your build.

Monsters do more than just attack—they can directly disrupt your board with Locks, Thorns, Spider Webs, and Black Holes.

As the space available for placing cards shrinks, battles become increasingly unpredictable.

How you build your board is up to you,

but how that board gets disrupted is up to the monsters.

Fuse your cards, expand your board,
engrave powerful effects, and find the perfect move.

What you build is more than just a deck.

It's your board.
