Exclusive: Palworld’s Adorable Creatures Invade Once Human in Massive Free Crossover Event

The open-world survival landscape is witnessing an unprecedented event as Starry Studio’s grim, post-apocalyptic title, Once Human, collides with Pocketpair’s viral sensation, Palworld. This major collaboration, which officially launched on October 29, 2025, sees the colorful, collectible creatures of Palworld—known as Pals—introduced as unique Deviations and cosmetic items into the dark, Stardust-ravaged world of Nalcott. This strategic partnership is a must-see for fans of both franchises, aiming to dominate the survival game genre’s engagement metrics and deliver significant, free-to-play value to players.

Industry analysts have noted this is a high CPC keyword event, capitalizing on the immense, sustained global search volume for both “Palworld” and “open-world survival game.” By merging the lovecraftian horror aesthetic of Once Human with the beloved, adorable creatures of Palworld, the developers are generating a unique gameplay loop designed to appeal to the widest possible audience of MMO and survival enthusiasts.

The event is a one-way crossover, meaning Palworld content is currently flowing exclusively into Once Human. This has allowed Starry Studio to deploy a large-scale content drop, fundamentally altering a portion of the game world with a new, temporary environment and introducing a wealth of free items. This move provides a compelling reason for new and existing Meta-humans to log in and optimize their in-game experience immediately.

Unveiling Paradise Island: A Palworld Ecosystem in Nalcott

The centerpiece of the collaboration is the new, limited-time map: Paradise Island. This exclusive island provides a temporary reprieve from the core game’s gloom, featuring a unique ecosystem where the monstrous Deviations of Once Human coexist, surprisingly, with the Palworld Pals.

Players will encounter familiar and highly sought-after Pals, including Cattiva, Chillet, and Chillet Ignis, with official announcements teasing “mystery Pals” awaiting discovery. Unlike typical event loot, the major collaboration items are being offered for free, ensuring all players can participate fully.

• Free Cosmetic Items: Players can claim a wealth of collaboration-themed rewards, including full fashion sets, unique furniture blueprints for base-building, eye-catching weapon charms, and customizable namecards and avatars. This focus on cosmetic rewards taps directly into the highly profitable digital customization market.
• Transformation System: A key gameplay mechanic introduced for the event is the ability to transform. Players can obtain five different Transformation Cookies to temporarily take on the form of both collaboration Pals and Deviations. For example, transforming into one of the Chillet forms allows other players to ride on your back, while becoming a Cattiva reportedly boosts gathering efficiency, adding a utility function to the fun.
• Exclusive Event Currency and Rewards: Engaging in activities on Paradise Island grants Paradise Coins. This event-specific currency can be redeemed for Legendary blueprints, Pal-themed furniture, and Starchrom, the game’s premium material, making participation essential for those seeking build optimization and high-tier resource acquisition.

High-Engagement Activities and Deviation Mastery

The Once Human team has integrated high-frequency, timed events to encourage continuous player engagement and cooperative MMO interactions within the new zone. These activities, available throughout the collaboration period, are designed to maximize the content’s value:

• Cattiva’s Island Party: Scheduled for every even hour from noon to midnight, Cattiva distributes gifts across the land, offering chances to earn collaboration Deviations, cosmetic items, and the coveted Paradise Coins.
• Great Party at the Paradise Plaza: Occurring every odd hour, this social event at the island’s center encourages players to dance and use special bubble guns to fend off invading Deviants, rewarding them with gifts and further resources.
• Deviation Master World Championship: A competitive element is introduced with this tournament, allowing players to register and test their Deviation training skills, offering a prestigious goal for the community.

The collaboration also coincides with the launch of the new PvE scenario, “Deviation: Survive, Capture, Preserve,” which heavily features the Deviation fusion system. This new feature allows players to merge Deviations with other creatures or even inanimate objects to create novel allies. The introduction of the adorable, yet potentially mutated, Pals from Palworld into this system offers tantalizing new possibilities for meta-builds and strategic combat planning in the wider Once Human universe.

This major, free open-world survival crossover solidifies both Once Human and Palworld as key players in the 2025 gaming news cycle. The event’s comprehensive structure, featuring a new map, unique mechanics like transformation, and abundant free rewards, ensures it delivers on the hype surrounding this unlikely union.

Given the depth of the new Deviation Fusion System and the inclusion of Palworld Pals as Deviations, would you like an analysis of how the new Cattiva, Chillet, and Chillet Ignis Deviations might best be utilized in a competitive PvE or PvP Once Human build?
