Popular Slay the Spire mod Downfall is getting a full Steam release. The mod will be downloadable via its very own Steam page, adding a new hero, a new game mode, and plenty of other content to Mega Crit Games' roguelite card-battler.
Why has this Slay the Spire mod received a full Steam release?
This news comes as part of a new Slay the Spire update. Mega Crit describes Downfall as one of the game's "most extensive and popular mods", and now it's got its own Steam page for you to wishlist it ahead of its March launch. Downfall will be downloadable for free on March 25th (assuming you own Slay the Spire, of course) and adds the brand new Downfall game mode, which tasks you with protecting the spire rather than slaying it. To do so, you'll need to control Villains, each of whom has their own pool of cards, relics, and potions. Downfall also adds a new Hero, new events, and lots more, so check it out if you love Slay the Spire and want more of it. Downfall should tide you over until the tabletop game comes along, anyway.

As well as the full Downfall release, Mega Crit also announced that Slay the Spire Steam deck compatibility is a go. The card battler can now join titles like Terraria and Hello Games' redemption story in being officially available for Valve's new handheld gaming PC. As part of this update, Mega Crit is also adding Steam Input support, which means the game should "work nicely out of the box" and shouldn't require any additional tinkering. You will need to enable Steam Input, but if you prefer to use the game's old controller logic, you can disable Steam Input as well.
What is Slay the Spire?
Slay the Spire is a roguelite deck-building game which Mega Crit describes as "the best single player deckbuilder we could [make]". The game features hundreds of different cards with which to build your deck, as well as plenty of relics to empower you and lots of different combat encounters with which to test your mettle. As a roguelite, it naturally also features daily modes so you can pit yourself against other players for a high score, as well as a layout that changes each time you play.

You can buy Slay the Spire right now on PC, PlayStation consoles, Xbox platforms, and Nintendo Switch (and it's also available on iOS, should you want to play it on your phone). The Downfall Steam page goes live on March 25th, but until then, you can still download the mod via the Steam Workshop. Be sure to take a look at it if you're looking for games to play on your new Steam Deck; it can be a fiendishly addictive title once you're into it.
