One year into early access, Jump Space is throwing open its doors for free. The co-op space shooter from Keepsake Games is playable at no cost on Steam from September 17 through September 21, and it arrives alongside an anniversary update that addresses some of the rougher edges players have been pointing at since launch.
For anyone who missed the Steam Next Fest buzz back in June 2025, the pitch is straightforward: you and up to three friends drop onto planets and stations, fight through hostile environments for loot and ship components, then return to your spacecraft to upgrade and repair before flying on to the next objective. Hand-crafted missions with randomized elements keep runs from feeling identical. Between planets, you might intercept enemy ships or take spacewalks through derelict wreckages. It sits somewhere between the squad tension of Helldivers 2 and the freeform space travel feel of No Man's Sky, and that combination is what drove over 500,000 players to its demo during Next Fest.

What the anniversary update actually changes
The headline addition is a full difficulty overhaul. The old five-tier challenge rating system has been expanded to eight threat levels, and the intent is not purely to make things harder. Keepsake specifically wanted to smooth out the progression curve and cut the frustrating difficulty spikes that some players hit mid-campaign. Early threat levels feel more forgiving now, but threat level 8 is described by the studio as "borderline impossible unless you're locked in, play smart, have endgame-level gear, and show great teamwork."
Enemy variety has expanded to match. Hostiles now come in color-coded tiers that signal danger at a glance, and modifier titles like "overclocked" or "bruiser" telegraph what you're walking into before you commit. There's also a new counter-cheese mechanic worth knowing: shooting ground enemies from the safety of your ship can now trigger them to board your craft and target ship systems directly. They'll leave the pilot seat, combat seat, and scanner station alone, so you won't get blindsided mid-flight, but your ship hardware is fair game.
Quality-of-life fixes that should have been there earlier
An auto-save system now triggers every time you jump to a new sector, which means mid-run crashes and sudden disconnects no longer wipe your progress. You can pick up a current mission from the main menu if something goes sideways. It's the kind of feature that feels table stakes for a game built around long co-op sessions, and it's good to see it land.
Player inventory has been restructured into three separate tiers covering weapons, consumables, and general storage, with the total slot count coming out higher than before. The old Multi-Tool has been replaced by the Materia Gun, now a standard loot weapon that can roll with various modules and offers infinite ammo as a backup option. Door interactions and repairs are handled by a separate gadget, which keeps the Materia Gun as a genuine weapon choice rather than a utility item you're forced to carry.
Keepsake also flagged "large stability fixes" in the patch notes, which is the kind of vague language that usually means the studio spent serious time squashing crashes that were hard to reproduce.
What comes next for Keepsake
The studio has signaled that details on the next major update will arrive in early October, with the update itself targeting a December window. Keepsake described ambitions to make it "as big and exciting as the Weapons Update," and dropped a hint that strong performance during this free weekend could accelerate some announcements. Whether that means new content, a feature expansion, or something else entirely, the studio is keeping it vague for now.
For multiplayer games in early access, free weekends tied to anniversary milestones tend to be the clearest signal that a studio is confident in where the product stands. Jump Space has had a year to patch, balance, and build on its Next Fest momentum, and this weekend is the practical test of whether that work shows.
The free access window closes after September 21. If you want to go in prepared, the Space Mavericks game page has the context you need, and the Space Mavericks strategy guides are worth checking before your first drop.
