Slay the Spire and Squad offered in September’s Humble Bundle

On Friday, Humble announced the September additions to its Monthly Bundle: Slay the Spire and Squad. They are available to download now, replacing the August bundle, which included Kingdom Come: Deliverance and Surviving Mars.

Kickstarter-backed tactical shooter Squad is still in early access on Steam, where it has averaged “very positive” reviews. (A launch is planned for 2019, according to developer Offworld Industries.) The studio has released periodic updates since it launched in 2015. As recently as last week, the game received a new modding toolkit and the Canadian Armed Forces faction.

In addition to offering its titular bundles, Humble also publishes games from indie developers. Slay the Spire is one such game. The roguelite deck-building game was developed by indie studio Mega Crit Games, and launched in early access in 2017. When it was officially released earlier this year, we gave it our Polygon Recommends badge for its challenging but rewarding gameplay.

The Humble Monthly Bundle costs $12 per month and usually includes eight to 10 games. The early unlock games are available to download as soon as they’re announced on the first Friday of each month, with the rest of the bundle revealed after orders close a month later. Humble promises a bundle worth at least $100. And unlike similar game subscription services like Xbox Games With Gold and PlayStation Plus, the games are yours to keep even if you cancel your subscription.

Along with the bundled games, a Humble Monthly subscription includes 20% off orders at the Humble Store and access to a library of DRM-free games. Called the Humble Trove, the collection includes favorite indie titles like The Sexy Brutale, Gone Home, and Limbo.

In addition, 5% of each Humble purchase is donated to charity; September’s bundle supports St. Jude’s Children’s Research Hospital.
