A Perilous Journey Awaits: WizKids Reveals ‘D&D Onslaught: Tomb of Horrors’ Expansion

For fans of board games and the perilous dungeons of Dungeons & Dragons, a new challenge is on the horizon. WizKids has announced a new expansion for their competitive skirmish game, Dungeons & Dragons: Onslaught, and it’s taking players to one of the most infamous locations in the history of the game: the Tomb of Horrors.

Titled Tomb of Horrors – Maps & Monsters Expansion, this new release is set to hit shelves in February 2026. Unlike the competitive gameplay of the core game, this expansion introduces a thrilling new mode: cooperative play.

What’s Lurking in the Tomb?

This expansion is designed to challenge players in new ways. In a desperate bid to survive, players must join forces to navigate the treacherous dungeon. Here’s a look at what this new expansion brings to the tabletop:

• Cooperative and Solo Gameplay: For the first time in D&D Onslaught, you can work together with your fellow adventurers to survive. The expansion also supports solo play, allowing you to test your mettle against Acererak’s deathtraps on your own.
• Randomly Generated Dungeons: The map layout and its dangers are randomly generated each time you play. This ensures that every delve into the Tomb is a unique and unpredictable experience, keeping players on their toes.
• New Components: The expansion includes four new map tiles, along with a host of new cards, tokens, and scenarios. This adds a wealth of new content to the game, providing a fresh and exciting way to play.
• A Classic Adventure Reimagined: The Tomb of Horrors is known for its lethality and cunning traps. This expansion captures the spirit of that legendary adventure module, bringing its notorious plot to the Onslaught gameplay system.

An Expansion, Not a Standalone Game

It’s important to note that the Tomb of Horrors expansion requires either the Dungeons & Dragons Onslaught: Tendrils of the Lichen Lich Starter Set or the original Core Set to play. The expansion does not include miniatures but comes with monster tokens. For players who love the visual appeal of miniatures, WizKids has made it easy to upgrade, with suggestions for miniatures from their various D&D lines.

The Tomb of Horrors – Maps & Monsters Expansion is a great way to add new life to your D&D Onslaught game, offering a challenging and highly replayable cooperative experience for one to four players. Get ready to face the traps and terrors of the Tomb of Horrors when it arrives in early 2026! You can preorder now from WizKids or your local FLGS.
