Vellum, developed by Alvios Games, is a cooperative action roguelike that casts players as Scribes defending an infinite library. Players enter mystical Tomes, cast ink-infused spells, and shape each run by choosing upgrades for both themselves and their foes. Key systems include deep spellcrafting, Signature Inks, and a customizable hub for persistent progression. The game targets fans of team-focused roguelikes who value short, tactical sessions and creative build experimentation.

What kind of game is Vellum?

In this game, you play as a Scribe who enters magical Tomes to fight the Torn, a force that threatens literature. Runs are designed as fast-paced roguelike sessions, roughly thirty minutes long, with a core loop of choosing spells, upgrading powers, and modifying enemy growth. The loop emphasizes iterative build-making and strategic choices, since players pick both their augments and the Torn Pages that strengthen foes.

Does it have a multiplayer mode?

Inside matches, Vellum supports 1–4 player online co-op with drop-in/drop-out functionality, enabling casual groups to join ongoing runs. Team mechanics include a Font System that lets Scribes invoke combined abilities to boost individual builds. The Illuminated Library acts as a persistent hub for researching talents and social interaction, while Storyboard mode provides a bingo-style boss rush intended for coordinated squads seeking focused endgame challenges.

What does the game look and sound like?

Within the presentation, the visual design leans on a literary aesthetic centered on ink, parchment, and stylized book motifs. The Illuminated Library provides a customizable hub space that ties meta-progression to the game world. The title is verified as Playable on Steam Deck and includes full controller support, which helps accessibility for controllers. Some players report visual clutter during intense combat, which can affect readouts in busy encounters.

How steep is the learning curve and what keeps players returning?

During progression, depth comes from over 300 powers and augments plus Signature Inks like vampiric Red or swarming Blue, so experimentation drives replay value. The game's twist of letting players choose enemy buffs creates a risk/reward cadence that shifts difficulty deliberately. Meta-progression through the hub and Storyboard boss runs provide long-term goals, making replayability hinge on build discovery and the evolving challenge each run presents.

Who should play Vellum?

Vellum is a rewarding choice for players who enjoy tactical, team-based roguelike sessions and iterative build experimentation. Alvios Games brings over a decade of multiplayer development experience, and community reception is listed as "Very Positive." However, players seeking single-player, narrative-driven RPGs may prefer a different style. Fans of Risk of Rain 2, Gunfire Reborn, and Hades should find Vellum worth trying.
