About the Game
Jump Space (formerly Jump Ship) is a mission based co-op PvE for up to 4 players, where you are the crew of a spaceship. Transition seamlessly from crewing the ship to on-foot exploration and space walks. Engage in intense battles both on the ground and in space, and always keep your ship upgraded and intact. Teamwork is key for survival and victory.
We love co-op games, and we love space. Jump Space is our attempt to make both work together.
Features
Jump across the universe - Select from a variety of hand crafted missions with random elements. No two runs will be exactly the same.
Seamlessly go on and off ship - Once you’ve jumped with your ship, you can switch seamlessly between operating your ship, space walking and on-foot planetary exploration, it just works.
Upgrade, maintain, repair - Manage your ship as you scavenge for parts to upgrade or repair it, and adapt it to fit your needs.
Fly with a crew, or go solo - Jump Space is best enjoyed with friends, but solo adventurers are welcome too.
Manage Your Jump Ship
Upgrade and customise your ship as you face off against the challenges of space exploration, and scavenge resources to ensure your survival. Reinforce your defences, adjust your energy output for speed or bolster your ship’s attack capabilities - the choice is yours.
Immerse Yourself in Space
Experience fluid gameplay as you switch from steering your ship out of an asteroid field to jetpacking towards an enemy vessel to sabotage its core. Seamlessly transition between exploration, combat and traversal.
Improvise and Adapt; Together
Go on missions with your friends and take on roles, from piloting to engineering and field exploration. Work together to overcome enemy attacks, extinguish fires on the command deck or adjust your ship’s power grid on the fly. There are no set classes in Jump Space, improvise and decide how you want to engage.

Official update history
Version 0.7.15.13 – Patch Notes
Released July 16, 2026
Okay, THIS one is the last Weapons Update-related patch for a while, we will be back in August after vacation to keep working full force on the next content update and fix more bugs.
Read our latest proper Dev Update to catch up on what our next plans are:
[dynamiclink href="https://store.steampowered.com/news/app/1757300/view/681880049901637756?l=english"]
Bug Fixes
Fixed EMP Shield Restore, the module that had no effect when equipped.
Fixed Shield Downtime not correctly reducing shield downtime.
Improvements
Added Bonus Damage ship modules since it was not in any drop tables.
Railgun damage now scales up with level and its extra-shot module grants a flat number of additional shots before recharge, rather than increasing magazine capacity
Corrected stat values for several modules, including Engine Turn Rate, Shield Emitter Stability, Ruptured Armour, and Dual-Burst Actuator
Fixed inaccurate or unclear descriptions on multiple modules, including Corrosion, Ruptured Armour, Melee Kill Rush, Dual-Burst Actuator, EMP Shield Restore, and EMP to Irradiation
Update 0.7.15.12 – Patch Notes
Released July 15, 2026
Balance Changes
Cure Critical condition at Med-Station: Materia cost has been reduced from 30 to 20.
Weapons
Bolt Accelerator: Ammo cost per shot reduced from 3 to 2, reload time reduced from 1.5s to 1.25s, and damage increased from 350 to 400.
Disruptor Laser: Damage reduced from 100 to 80.
Ship Missile Launcher: Missile damage doubled from 500 to 1000.
All pilot and multi-turret weapons now correctly scale damage based on their own level progression, meaning more damage. Previously they were incorrectly using on-foot damage scaling.
Modules & Abilities
Splinter Shell: Now correctly increases damage instead of reducing it.
Shotgun: Slight buff to higher rarity tiers to improve progression feel.
Emergency Vent: Damage and level scaling increased.
Chain Link Module: Chain Link used to chain to enemies through an AoE hitbox. It now fires real projectiles from where the initial projectile hit, meaning it can trigger status effects and interact with other systems properly.
Chain Link for Ship Weapons: Now also chains with real projectiles instead of AoE.
Bug Fixes
Fixed an issue where the health bar would display the death timer instead of your actual health after being revived.
Fixed the bonus objective calculation for the Escape Finale mission, which prevented you from getting every last crate and bonus rewards..
Fixed an audio error that occurred when a buddy NPC was using the Vulcan special weapon.
Fixed a broken description on the Extended Railgun Magazine module.
Fixed incorrect descriptions for the Micro Bullets and Larger Bullets
Updated the Shotgun Ship Module description to more clearly explain what it does.
Visual & Audio
Reduced the size of the Sear status effect visuals.
Made the Corrosion effect less visually noisy.
The Heavy Raptor enemy now correctly displays status effect visuals when affected by status conditions.
Improvements
- Boarding Blitz damage increased
Bug Fixes
- Fixed an issue where loot that rolled a high rarity could land on an item that only exists at low rarity, downgrading the drop to standard. This caused far more standard items than intended at higher challenge ratings, you should now see fewer standard drops and more items at their intended rarity.
- Fixed Ship Minigun spinning animation playing when not firing
- Fixed Boarding Blitz explosion not centered on the target ship
- Fixed med-stim and other stackable consumables so they stack correctly when picked up
- Single destination missions now give rewards in line with Salvage missions
Improvements
Weapons & Modules
- Corrosion Overhaul: Corrosion has been reworked to better fulfill its intended fantasy of rapidly stacking debuffs that deal big damage when players reach a high stack count. The status effect now lasts longer (4 → 8 seconds) and activation chances have been significantly improved across the board, encouraging stack buildup. Damage has been decreased per stack on all Corrosion Modules. We fixed a visual issue where the reported damage of corrosion modules was half of what they actually did.
- Shotgun Center Pellet: Shotgun weapons now always fire one pellet directly at the center of your aim for more consistent and satisfying feedback.
- Additional bullets: Added the amount of damage reduction they caused into the description. Previously this was hidden information.
Loot & Economy
- Materia Ingots: Lowest-tier Materia Ingot pickupables have been removed from CR4 and CR5 missions. Higher-tier ingots now drop more frequently in CR3, CR4, and CR5 missions.
- Mission Reward Changes: Crude and Flawed Materia Ingot mission rewards have been increased at higher challenge ratings
- Single Missions — CR3: Crude 1 → 3 · CR4: Crude 0 → 4 · CR5: Crude 0 → 5
- Salvage Missions — CR3: Crude 1 → 3 · CR4: Crude 0 → 4, Flawed 2 → 5 · CR5: Crude 0 → 5, Flawed 1 → 6
- Regular Missions — CR2: Crude 3 → 4, Flawed 4 → 3 · CR3: Crude 2 → 5 · CR4: Crude 0 → 5, Flawed 4 → 6 · CR5: Crude 0 → 6, Flawed 3 → 8
Gameplay & Maps
- On-Foot Combat Pacing: Updating wave spawning pacing in On-Foot enemy encounters for solo players and further increasing the breathing room between the waves.
- Data Center: Updated navigation and fixed a potential softlock that could occur when waves were still active.
- Sulfur & Lockdown Maps: Fixed navigation issues in the Sulfur and Lockdown levels.
Balance Changes
- Ember Slugs: Damage increased across all tiers. Damage cap has also been slightly raised.
- Chain Link: Gains one additional bounce and deals slightly more damage per bounce (damage reduction reduced by ~10%).
- Sear: Damage increased, making Sear hit harder at every level and tier.
- Flechette Rounds: Reduced projectile count gained per upgrade and reduced spread improvement per upgrade. Damage reduction now correctly applies. Overall effectiveness has been reduced as the module was overperforming.
- Corrosion (Ship Weapon): Increased activation chance on each tier. Increased base damage on each tier. Lowered damage scaling on each tier. This results in a damage reduction per dot but allows the module to fulfil the high stack count play style we aim for.
- Basic Damage Module: Reduced overall effectiveness.
- Shell Duplicator: Reduced pellet count per tier and increased damage reduction per tier.
Bug Fixes
- Additional bullets: Fix an issue where damage reduction was not applied the way it should. They should now be closer to our intended design.
- Static Cascade: Reworked. Now reliably applies EMP on a critical hit. Has been removed from full-auto weapon drop-tables to prevent balance issues.
- Missile Launcher: Now correctly displays stats and properly scales damage with equipped modules.
- Minigun & Heavy Cannon: Now benefit from damage scaling leveling.
- Corrosion: Corrosion can no longer last-hit an enemy.
- Corrosion: Corrosion at high stacks could previously cause performance issues.
- Ship Fires: Fixed an issue where fires could erupt on a ship while its shields were still active. Note: A failing radiator can still cause fires regardless of shield status.
- Chain Link: Fixed a bug that caused Chain Link to be completely disabled.
- Buddy Bot: Fixed an issue where Buddy Bots On-Foot weapon dealt 0 damage when hitting a critical point. He now correctly deals +50% damage on critical hits.
- Single Missions — CR3: Crude 1 → 3 · CR4: Crude 0 → 4 · CR5: Crude 0 → 5
Changelog
July 6th, 2026
Bug Fixes
Fixed an issue where explosive barrels did not disappear for some clients
Fixed several emergencies not being synced for client players

(Update: We noticed that the Chain Link "Chain to nearby enemies" Module is broken, making it have blank text and weapons with it might deal 0 damage if the Module has points in it. Will be fixed for next hotfix.)
Features
Downed players now automatically get revived on hyper jump to next sector if there is no way to revive them (no crew lives and only one core life left)
Balancing
Turn rate module - reduced efficiency across the tiers and lowered max lvl from 5 to 4. The level cap was lowered to match the other basic modules and had its efficiency lowered. The idea is to make it a bit less capable of removing the flaws of some engines and act more like a slight boost.
Microplasma engine, boost increased to 4, recharge timer decreased to 5, max boost speed increased to 120% - Intention is for this engine to live more on its boosts than normal engine performance. It currently is missing a bit of a place in-between the other engines and this is a first step to make it a bit more unique.
Nitro pulse engine, boost time decreased to 1.5 from 2, and decreased boost recharge from 10 to 9, acceleration reduced from 75% to 50%, Turnspeed reduced from 75% to 65%. Max boost speed and max speed modifier reduced from 140% to 125%. - The nitro pulse engine just overperformed compared to other engines. This is a step to bring it more inline with the others while still keeping its higher top speed.
Drift Phase engine - Increased boost recharge from 7 to 8
Mass Ejector engine - Reduced boost recharge from 6 to 5
Reduced efficiency on engine speed and turn rate modules to address balance issues at high speeds. This should fix the bug of ships flying too fast for networking to keep up with, resulting in visual "teleporting ship" for clients in the lobby.
Sear module change:
Standard, increased damage per level scaling common from 5 to 10
Refined, reduced sear proc growth from 10% to 7.5% and reduced max value rolled from 15% to 12.5%. Increased damage scaling from 10 to 15
Advanced, Proc chance scaling reduced from 15% to 10%
Superior, Proc chance max value reduced from 30% to 22.5% and growth reduced from 20% to 12.5%Reduced spread on Flechette Rounds by half. This is also to fix a visual bug of muzzle flashes filling the whole screen.
Splintershell module spread reduced by 1
Improvements
On-foot enemy wave spawns now have longer breathing times between waves when playing Solo or in a Duo crew
Increased explosive barrels damage to enemies to keep up with the higher CRs and new stronger versions of enemies
Removed the materia maximum cap (previously 250)
Engine item modules reverted to using multipliers instead of additive values, which caused issues with UI displaying wrong speeds
Weapons Update Hotfix 6 - Reducing Difficulty and Deadzone Settings - v0.7.15.8
Over the week since we launched the Weapons Update, we have been monitoring which modules and status effects may be too powerful or too weak, and one thing that stood out is that the Corrosion status effect is vastly more powerful than we originally intended. For that reason we are bringing it in line with the other effects, at the same time as we are buffing some of the weaked effects and the base weapon damage of on foot weapons.
Deadzone settings for controllers have been added, we know many players have been waiting for this.
Thank you for leaving your feedback on combat difficulty after the Weapons update dropped, we will continue to monitor but we hope this improves your experience during objectives that spawn waves of ground enemies.
For those who feel Ingots should be refunded when an older, already upgraded blueprint is abandoned for something better - we are working on some kind of refund mechanic so stay tuned for that.
We are aware of Engines not being affected by their Modules and the math of stat Modules not lining up perfectly - we will have a patch for this early next week
Features
Added individual deadzone settings for the left and right sticks in the gamepad options menu
Improvements
Sear & Corrosion Balance: Sear and Corrosion status effects have been brought more in line with each other. Proc chance and Damage for Corrosion has been lowered. Corrosion base duration increased by 1 second to compensate for its damage reduction. Sear has had damage increased across all tiers and now ticks damage as often as Corrosion does.
Weapon Scaling: Damage scaling improved across multiple weapons to be higher when fully upgraded.
Improved Damage Module: We have reduced the effectiveness of this Module, compensating with the above Weapon Scaling change. This is to make damage stay the same, but prevent weapons without "Improved Damage %" from feeling useless due to dealing way less damage.
Slightly Reduced Magasize Size: To keep guns feeling distinct, all guns got reduced magazine size in different capacity. One example being, the LMG should have the largest mag by far. This was compensated by the damage change.
Ship Modules: Several components can now access additional damage affinity Modules simultaneously
Targeting Module: The Targeting Module component will now only drop at Green rarity, due to lacking any stats and unique Modifiers.
Buddy Bot projectile damage increased by 33% (15 > 20)
Rocket Drone missile speed reduced (29 > 23) and explosion radius reduced (6 > 5) for better balance
Reduced the amount of Drone spawns in waves
Bug Fixes
Fixed a soft lock that could occur at Wave 20 in Data Center
Fixed an issue where object outlines would incorrectly remain visible during cinematics
Fixed Rocket Drones and Sniper Drones not properly resetting their wind-up animations when they stopped firing
Laser ship weapons can no longer spawn with multishot Module
The design team who have all worked a ton on crafting the Modules has a few words on these changes:
"Hello! Let's talk about some ideas and thoughts around two of our status effects, namely Corrosion and Sear. Corrosion is currently very powerful, to the point of making everything else kind of irrelevant.
So to make it easier to balance the rest of the effects, it is being hit with a reduction in damage and proc chance. BUT, it is gaining a slightly longer lifetime to make it a little easier to still keep a decent stack number up.
Corrosion is meant to be an effective single-target killer, but in its current configuration it does that, and everything else. I understand that many have seen Corrosion as the gold standard for weapons now, and there might be some disappointment with its nerf. But hopefully the other changes made will mitigate it a bit.
Speaking of other changes, we've upped how much damage that weapons gain from just being leveled up, going from 2.5 to 4.5 percent. This comes in tandem with a reduction in effectiveness of the improved damage module, but from testing we've gathered that the effective damage loss is matched by the gain in damage from the level buff.
Another smaller change coming along with this is Sear being buffed. We're working on more changes to it, but this is what we have for now. Besides a damage boost across the board, both its shown damage and how often it ticks this damage is increased. It is getting a fixed lifetime across levels and tiers; with this it will provide much more reliable damage.
Our intention with Sear is for it to be a thing to handle multiple enemies vs. corrosion's single-target damage. Spraying down a horde to light them on fire so you can focus on other ways of staying alive while the fire does its job, while corrosion stacks up damage on the bigger targets. With these changes, we hope to give more defining roles for these two effects. The other status effects will get more love as well, but it will be easier to focus on a few at a time to give them attention.
Now, early on in this update there will probably be some bigger swings in balance as we make a more interesting balance curve for everything, but we will be observant and look at how these effects impact the larger statistics over the weekend and be ready to address issues next week!
Thanks for helping us make this as great a game as possible."
