Build, manage, and grow your dream zoo in Planet Zoo. Animal welfare, habitat design, guest flow management, and staff scheduling are all deeply simulated. A huge selection of Animal Packs (Wetlands, Arctic, Asia, Americas, Aquatic, and more) are each at 50% off — though buying all the DLC represents a significant investment even at these prices.
Planet Zoo has extensive paid DLC that isn't included with the base game. We recommend starting with just the base game ($13.49) before deciding how many Animal Packs to purchase.
4. Jurassic World Evolution — Deluxe Edition
Another Frontier simulation — this time build your own dinosaur theme park. Jurassic World Evolution tasks you with managing dinosaur enclosures, guest facilities, and the inevitable containment failures that follow. The Deluxe Edition includes additional dinosaurs and cosmetic content and is discounted as part of this sale.
5. FAR: Changing Tides — Deluxe Edition
An atmospheric, side-scrolling adventure through a post-apocalyptic ocean world. FAR: Changing Tides is a quieter, artistic experience compared to the simulation titles — you sail a ship through a flooded world, solving environmental puzzles along the way. The Deluxe Edition is discounted in this sale for those who want the complete package.

What Is the Warhammer Skulls Event?
Skulls is an annual Steam gaming event dedicated entirely to Warhammer-licensed games — typically running in late May to early June. It features game announcements, free DLC giveaways, and significant discounts across every major Warhammer game on Steam.
The timing of Frontier's May Sale is no accident: Chaos Gate — Daemonhunters is one of the highest-rated Warhammer strategy titles in recent years, and its 90% discount during Skulls is one of the most compelling single-game deals of the event.
Community Reactions
""Chaos Gate for four fifty? Did something break? XCOM fans owe it to themselves to buy this immediately." — Reddit r/patientgamers
""Planet Zoo was already worth it full price. At 13 bucks it's embarrassing not to have it. Just don't buy all the DLC at once, your wallet will cry." — Steam Community Hub
""Planet Coaster 2 has genuinely gotten better since launch. The May update added new management tools and the sale makes it impossible to say no now." — Reddit r/PlanetCoaster
Buying Tips
Best value route: Grab Warhammer 40K Chaos Gate Standard at $4.49 first. If you love it, the Castellan Champion Edition upgrade is also cheap. Start small, add DLC later.
For Planet Zoo, the base game at $13.49 gives you hundreds of hours of content. Animal packs can be added later as individual purchases when specific animals appeal to you — don't try to buy everything in one go.
Sale Ends June 4 — Don't Wait
The Steam Frontier May Sale runs through June 4, 2026. With over 114 titles discounted and some deals reaching 90% off, this is one of the strongest publisher sales of the spring gaming calendar. Whether you're into tactical strategy, park management, or zoo building, there's likely something in this sale that deserves a place in your library.
