Humble Bundle has rolled out a fresh limited-time game pack called Sovereign Sandbox, bringing together eight highly rated sandbox and simulation games that are Steam Deck compatible. Every title in the collection is listed as Steam Deck Playable or Verified, making this bundle an easy pick for handheld gamers looking to expand their library with games that run well on the Steam Deck.
In total, the Sovereign Sandbox bundle is valued at $195 based on standard Steam pricing, but it’s split into two pricing tiers so you can jump in at a lower cost and upgrade if the bigger games catch your eye. The bundle is scheduled to expire on May 10, 2026, and the included Steam keys must be redeemed before April 29, 2027.
Two standout games help anchor the collection, especially for fans of deep management gameplay.
The Universim is a colony sim and city builder from Crytivo that puts you in the role of the Creator, guiding a quirky species called the Nuggets from their earliest days to becoming space-faring colonizers. It leans heavily into planet management with procedurally generated worlds, resource balancing, ecosystem control, and more than 200 technologies to unlock. You also get access to over 15 divine powers, letting you influence your civilization with everything from nurturing growth to unleashing disasters like lightning strikes and tornadoes. On Steam, it’s priced at $29.99 and has around 10,500 reviews with roughly 80% positive feedback.
Prehistoric Kingdom is a zoo management and tycoon-style simulation from Blue Meridian, published by Crytivo, focused on building and running a prehistoric wildlife park. The game emphasizes designing enclosures, expanding your park, and reviving more than 60 scientifically accurate extinct species. You can incubate, breed, and raise animals as they grow from babies to adults, adding an extra layer of long-term planning for park layouts and animal care. It also sells for $29.99 on Steam and has about 5,700 reviews, with around 89% rated positively.
Beyond those highlights, the bundle’s eight games are divided across two tiers.
The $10 tier includes four items:
Nova Lands
Wildmender
Ctrl Alt Ego
My Little Universe: Complete Edition
The $18 tier adds four more items, bringing the full bundle to eight:
Prehistoric Kingdom
Worshippers of Cthulhu
The Universim
Overthrown
For players who enjoy sandbox creativity, base-building, automation, colony management, and tycoon-style progression—and want games that are confirmed to work well on Steam Deck—Sovereign Sandbox is positioned as a strong value, especially if you’re looking to pick up multiple well-reviewed titles in one go before the bundle deadline.
