If you want a co-op survival game to play before State of Decay 3, choose by the part of the experience you most want now: 7 Days to Die for zombies and base defense, Sons of the Forest for horror exploration, Grounded for a shared world that can persist between sessions, or Valheim for open-world exploration and crafting. None is established as a substitute for State of Decay’s survivor-community management.
Xbox Wire’s June 7, 2026 gameplay-reveal article says the team is aiming for a 2027 release; that is a target, not a confirmed launch date. The reveal describes solo play or shared-world co-op for up to four players, settlement construction, maintaining a survivor community, and fighting a zombie threat in an open-world survival sandbox: Xbox Wire’s State of Decay 3 gameplay reveal.

Choose by the part of State of Decay you want to approximate
The announced design combines several things—zombie combat, settlement building, and managing a survivor community—so no single recommendation here covers the whole mix. Use this comparison to narrow the choice around your group’s priorities.
| Game | Best fit | What the cited source establishes | Main difference from State of Decay 3 |
|---|---|---|---|
| 7 Days to Die | Zombies, scavenging, crafting, and base defense | GamesRadar’s 2026 crafting guide includes it among zombie survival games and lists PC, PS5, and Xbox Series X/S. | It is a genre fit, not an established equivalent to survivor-community management. The cited source does not establish crossplay details. |
| Sons of the Forest | Co-op horror exploration, crafting, and building | The Steam listing describes surviving alone or with friends in an open-world survival-horror game and tags it for co-op and base building. | Its horror setting and focus differ from State of Decay’s community and settlement emphasis. The cited listing is for Steam/PC. |
| Grounded | A group world that can continue between sessions | Obsidian describes it as a multiplayer survival-adventure and says Shared Worlds preserve progress so play can continue when the original host is absent. | Its shrunken-backyard premise has a very different tone and setting from a zombie apocalypse. |
| Valheim | Open-world exploration and survival crafting | The official site describes player-hosted servers and survival play with others; its support FAQ discusses crossplay and says versions continue to be updated at the same pace. | Its Norse fantasy setting and exploration-and-crafting emphasis differ from State of Decay’s modern zombie community loop. |
For zombies and base defense: 7 Days to Die
Start here if the zombie threat, scavenging, crafting, and defending a base are the elements you want most. GamesRadar’s 2026 guide includes 7 Days to Die among zombie survival games and lists PC, PS5, and Xbox Series X/S: GamesRadar’s crafting survival games guide.
#1 Best Overall
- Capture and Tame Dinosaurs: Discover over 100 different dinosaurs and prehistoric creatures on the island, finding ways to tame them into useful additions for your tribe's dino herd
- Survive Above All: Hunger, thirst, basic safety, and protecting yourself from the weather are all part of the game
- Harvest, Hunt and Build: Cut down trees and turn them into a basic home, which you can quickly expand into a Jurassic estate. Hunt for meat, scavenge for plants (or start your own garden!)
- Customize Everything: An extensive crafting system invites you to mix and match materials scavenged from the island, while also modifying the colors, textures, shapes, and styles
- Explore the Island: Solve the mystery of The ARK as you explore this massive island, discovering Explorer's Notebooks (filled with clues!) throughout
That makes it the closest fit on this list by genre, not a confirmed stand-in for State of Decay’s survivor-community management. Check the current store listing for your platform and edition, and confirm whether everyone in your group can play together; the cited guide does not establish crossplay specifics.
For co-op horror exploration: Sons of the Forest
Choose Sons of the Forest if your group wants survival horror, exploration, crafting, and building rather than a modern zombie-community loop. Its Steam listing describes struggling to survive alone or with friends in an open-world survival-horror game and includes co-op and base-building tags: Sons of the Forest on Steam.
Rank #2
- New Pointstreak system that rewards players both for landing kills and completing objectives
- Weapons proficiency system that allows you to customize your favorite weapons, making them more effiecent in any map or mode
- Online/offline 2-player co-op Special Ops Survival mode that earns you experience through 16 frantic objective-based missions
- New play modes, including: Kill Confirmed mode, Team Defender mode and user generated match modes
- Integration with 'Call of Duty: Elite,' an online multiplayer oriented service launched simultaneously with Call of Duty: Modern Warfare 3
The cited listing is for Steam/PC, so do not assume the same availability on consoles. Its horror premise is also a substantial tonal change from State of Decay.

For a persistent group world: Grounded Shared Worlds
Grounded is worth considering when the practical issue is keeping a group world going even when the person who started it is offline. Obsidian describes the game as a multiplayer survival-adventure and says Shared Worlds preserve progress so the world can continue without its original host: Obsidian’s Grounded page.
Rank #3
- COOPERATIVE SURVIVAL GAME – Work together to endure post-apocalyptic dangers.
- EXPLORE THE WASTELAND – Randomly generated maps build out as you explore, triggering events and revealing monsters.
- 6 SURVIVOR CLASSES – Play one of 6 survivors with unique abilities and effects! Find synergies and unique strategies with different combinations.
- MULTIPLE APOCALYPSE SCENARIOS – four unique scenarios allow for lots of replayability. Face up against monsters, zombies, mutants, and more
- SOLO OR GROUP PLAY – Supports 1–6 players with roguelike replayability.
Its shrunken-backyard setting is not a zombie apocalypse, and the Shared Worlds feature addresses continuity between sessions rather than reproducing survivor-community management.

Pick Valheim if exploration, crafting, and surviving together in a player-hosted world matter more to your group than zombies. Its official site describes player-hosted servers and survival play with others, while its support FAQ covers crossplay and says versions continue to be updated at the same pace: Valheim official site and Valheim support FAQ.
Rank #4

The Norse fantasy setting and emphasis on exploration and crafting make it a different kind of survival game from State of Decay. Because platform and crossplay needs depend on your group, verify the current store and support information for the platforms you plan to use.
Quick Recap
Best Value
Check these details before choosing together
- Which gameplay element matters most? Choose 7 Days to Die for zombies and defense, Sons of the Forest for co-op horror exploration, Grounded for a world that can persist between sessions, or Valheim for open-world crafting and exploration.
- Can everyone play on their platform? Confirm the current edition and platform for each player, then check whether the game supports the cross-platform setup your group needs. The sources cited here do not verify full platform-by-platform crossplay for every title.
- Does your group need the host to be online? Grounded’s Shared Worlds specifically address continuing a world when its original host is absent. Valheim’s official site describes player-hosted servers; check the current setup details if hosting requirements are a deciding factor.
- Is the setting a deal-breaker? The choices range from zombie survival to horror and fantasy. If the modern zombie-community premise is essential, the other games share only selected survival elements, not the full premise described in the State of Decay 3 reveal.
