Indie Spacefaring Adventure ‘Jump Space’ Hits 250,000 Players in its Debut Weekend, Among Top 5 Best-Sellers Globally on Steam

With a Very Positive 90% rating on Steam and reaching over 21,000 peak concurrent players in its opening Early Access weekend, Jump Space has officially left orbit!

Stockholm, September 23rd, 2025 — Keepsake Games, a Swedish game development studio founded by veterans from Hazelight, Mojang, and Coffee Stain, is thrilled to announce that over 250,000 players have already taken to the skies to play Jump Space in Early Access.

Since launching into Early Access on Friday 19th September, Jump Space has seen over 21,000 concurrent players on Steam and ranked among the top 5 best-selling games of the weekend. Reception has been fantastic as well, with it currently sitting at 90% Very Positive rating on Steam. These milestones reflect the huge enthusiasm with which the game has been met and means Keepsake Games is fully committed to delivering its Early Access roadmap.

Players can expect a host of exciting new content, including an expanded intergalactic storyline, high-octane new mission types, colossal enemies, and vast new sectors to explore. This will come alongside the introduction of multiple new ships, weapons, player traits and regular quality-of-life improvements that will see the Jump Space universe continue to flourish.

Jump Space, formerly known as Jump Ship, is a mission-based co-op PvE adventure where players seamlessly transition from crewing their spaceship to engaging in on-foot exploration and intense spacewalks. The game challenges players to survive each mission, protect their ship, and collect valuable resources, blueprints, and weapons along the way.

Key features of Jump Space include:

• Modular Exploration – Players experience multiple “jumps” throughout each adventure, allowing players to dip in and out of handcrafted adventures with randomised events and modifiers.
• Seamless Adventuring – Players will be required to think on their feet to operate their vessel. Crewmembers can leave the ship at any time to repair the outer deck, embark on spacewalks, or jetpack toward enemies, without any loading screens.
• Ship Maintenance and Upgrades – Teamwork is the name of the game. Players earn blueprints and materials to upgrade their ship for future adventures, so crews must collaborate to collect as much loot as possible and ensure their survival.

“We have been absolutely blown away by the response to Early Access so far” said Daniel Kaplan, CEO at Keepsake Games. “Seeing 250,000 players jump into the game and join the Atiran resistance has been incredible and we’re overwhelmed with the positive feedback from our community. This has given the team huge motivation to continue building on this momentum and deliver even more great experiences for our fans.”

Jump Space is available on PC and Xbox now ($19.99, £16.75, €19.90). For more information, visit the official website or follow Jump Space on Discord. You can find the official press kit here.
