Salt Lake City, USA, September 29th, 2026 – Snowfall Games is proud to announce their upcoming cryptid deck-building auto-battler Portentum will launch on Steam Early Access October 28th, where it will be free-to-play. Portentum combines original hand-drawn cryptid artwork with deep deck-building strategy, letting you hunt for broken combos using legendary creatures from around the world, like Bigfoot, the Jersey Devil, Mothman, the Chupacabra, and of course, Jimothy. If somebody’s uncle saw it in the woods in 1973, there’s a good chance it’s a card in Portentum!
The rules of Portentum are simple: assemble a warband and win 10 rounds of battle. Build your deck of 30 cards, each containing a cryptid or mushrooms, then make strategic decisions with each hand you’re dealt, as you compete against another player’s warband.

Each cryptid is equipped with its own unique ability to deal damage, heal, summon a minion, manipulate the dice, and many other one-of-a-kind effects. Abilities can trigger upon a roll of the dice, another ally taking damage, or an enemy healing an ally. There are endless combinations and broken strategies to be discovered.
Once you’ve assembled your deck, head to the shop to deal a hand from your selected deck for that run. Spend gold to play cards from your hand, mobilize a five-slot warband, and then send your squad of monsters out to fight! Win ten rounds to achieve victory. Lose five, and you’re out.
Portentum’s meta is ever-evolving, as every warband you create joins the pool that other players face. As you keep playing and earning card packs, entirely new deck-building possibilities and obscenely killer combos will enter the fray, providing an endless array of strategic possibilities and challenges!
Portentum’s meta progression is built around long-term collection growth and competitive ladder play. Expand your card pool through booster packs, earned through gameplay or purchased via the game’s virtual currency system. These cards feed directly into both deck construction and strategic experimentation. This structure is supported by an asynchronous PvP system that removes queues and timers entirely, allowing you to engage in competitive matches at your own pace across multiple platforms and play sessions.
“We debuted Portentum to PAX West attendees earlier this month and drew an excited crowd through all four days of the event, with the most common question being: when’s it coming out?!“ Many said it would be a great Halloween game, which was what we’d been thinking anyway, so we’re going to launch Portentum on October 28th,” said Jaden Holladay, Co-Founder and Engineering Director at Snowfall Games. “Better yet, you won’t need to wait that long to try it, as we’ll have a demo available during Steam Next Fest running October 19th-26th, so you can start your next cryptid-collecting, card-battling pastime very soon!”
