About this game
Survive where Sol grows distant
Sol Survivor is a persistent multiplayer space-survival sandbox about building a foothold in the outer Sol system. Start alone, host a world for friends, or join another crew through Steam lobbies, then expand from a fragile EVA work site into a functional orbital habitat.Build the station piece by piece
Construct with modular habitat panels, octagonal tube sections, endcaps, coverings, mounted devices, routes, lights, batteries, screens, buttons, wires, pipes, and other station systems. The project direction is focused on structures that physically exist in the world, persist across saves, and can be expanded into larger player-built constructs.Work outside the airlock
Astronaut movement is built around zero-g EVA, Newtonian motion, suit control, damping, and construct anchoring. The goal is for players, offline bodies, and future NPCs to remain physically tied to moving constructs unless they actively thrust away.Host persistent worlds
Sol Survivor is designed around saved worlds, Steam lobby hosting, joining, invites, visibility options, lobby chat, and multiplayer synchronization. A hosted world is not just a match; it is a shared place that can persist, reload, and grow.Current feature direction
- Solo, host, and client session flow.
- Persistent saved worlds and player identity records.
- Steam lobby flow, chat, hosting, joining, invites, and password options.
- Zero-g astronaut traversal and construct-aware movement.
- Creative-mode modular habitat construction as the baseline for the survival pass.
- Saturn-ring-inspired outer-Sol setting with dirty ice rubble, station building, and EVA hazard.
- Systems-first station gameplay: power, lighting, devices, routed links, atmosphere, coverings, and mounted equipment.

Big Changes!
New Astronaut ModelReplaced the previous astronaut with a new, higher-quality modular character.Added a detailed spacesuit with a transparent helmet, backpack, boots, and visible face.Improved astronaut proportions and alignment with the player’s physical collision area.Corrected characters appearing too small, too large, or floating above platforms.Improved visual consistency between local and remote players.First-Person ImprovementsPlayers can now see their arms, body, legs, and boots while looking down.Fixed the camera appearing inside the player’s head, helmet, or backpack.Hidden first-person equipment continues to appear correctly to other players.Improved body alignment with the player’s viewpoint in both gravity and zero-gravity environments.Animation ImprovementsAdded a new configurable animation system for player movement and actions.Corrected the default standing pose.Added dedicated support for:Standing idleWalking and runningBackward movementStrafingWeightless movementJumpingPunching and other actionsImproved transitions between grounded and weightless animations.Animation changes now remain aligned with the player’s camera, reducing sudden visual shifts.Helmet and Headlight FixesImproved helmet transparency and lighting.Removed dark patches caused by the helmet light shadowing the player’s own helmet.Corrected the headlight’s position and viewing direction.Fixed an illuminated grid pattern that could appear around another player’s mouth.The headlight continues to cast normal shadows on the environment and other players.Remote Player FixesCorrected remote players appearing above the platform they were standing on.Improved remote player scale, grounding, and viewpoint alignment.Corrected head and body orientation when players look around.Improved remote presentation while floating in zero gravity.Solo World FixesSolo worlds no longer require Steam to be running.Fixed solo games becoming stuck at Loading Game — 15%.Fixed saved constructs failing to load wh...Read full article on Community Announcements (Eviltek2099)Patch NotesOfficial
Keybinds, Video Settings, Build Controls, and Performance Tools
This update focuses on control customization, clearer building/removal behavior, expanded video options, and new performance diagnostics to help tune larger stations and constructs.Keybind System OverhaulThe keybind menu has been rebuilt to make controls easier to manage.Added keybind categories with a page selector.Added primary and secondary bindings for each action.Added support for keyboard, mouse, mouse wheel, and modifier-based bindings.Added keybind search by action name or by pressing an input.Added a keybind reset-to-defaults button with confirmation.Combined duplicate inventory/bag controls into a single Inventory action.Added missing bindings for chat, find players, debug tools, building actions, selection tools, and workshop placement controls.Hotbar labels now show only the primary binding to keep the toolbar readable.Building and Delete ControlsBuilding removal has been reworked to be more deliberate and safer.Added a bindable Delete Mode Modifier.Default: AltHolding this key switches build tools into delete mode.While in delete mode, the selected removable object is highlighted red.Left-click performs the delete action while delete mode is held.Added optional Quick Delete keybind for players who want a single-button delete action.Default: unbound.Right-click is now reserved for secondary/cancel behavior instead of being the universal delete button.Removal is now tool-scoped:Panel tools remove panels.Window tools remove windows.Door tools remove door-frame parts.Device tools remove matching devices.Covering tools remove coverings.Panels cannot be removed until attached coverings/devices are removed first.Fixed cases where removing one build type could accidentally remove a different type, such as windows affecting door frames.Video Settings ExpandedThe Video menu now includes more performance and quality options.Added controls for:Graphics presetVSyncFPS limitRender scaleCamera anti-aliasingMSAAShadowsShadow distanceTexture qualityVista qualityPost pro...Read full article on Community Announcements (Eviltek2099)Patch NotesOfficial
Construction Sync and Copy/Paste Workflow Update
Construction Sync and Copy/Paste Workflow Update This update focuses on multiplayer construction reliability, copy/paste workflow polish, save-preview handling, debris collection, and new performance debugging tools. Major Changes Selection paste now builds itself into the world. Pasted content is reconstituted in stages instead of relying on a long ghost animation. Panels are built first, then mounted devices, wires, and pipes are added after their supporting panels exist. Multiplayer paste visibility improved. Other connected players can see paste preview positioning, nudging, rotation, commit progress, and the staged build as it happens. Selection Tool usability improved. Selection targeting range has been increased, copy/cut actions now provide HUD feedback, and the rotation/anchor cube now appears on the side of the panel you clicked. Hosted-world save identity improved. Joined hosted worlds now resolve by stable world identity instead of creating repeated local save entries with the same name. Save previews improved. Manual saves refresh the preview image. Autosaves and exit/runtime saves only create a preview when one is missing, preserving intentional player-composed screenshots. Multiplayer and Sync Fixes Improved construct-root synchronization during client loading and world activation. Queued live construct motion while clients are still restoring baseline/catchup state, then applied the newest queued motion before interaction begins. Panel placement and removal deltas now include affected construct-root records so clients can interpret new panels against the correct root state. Selection paste and cut operations now route through host-authoritative replication instead of mutating only the local client. Free-space panel placement from non-host clients now waits for host authority instead of creating unsafe local-only construct roots. Copy, Paste, and Selection Tool Pasted panels, devices, wires, and pipes are now staged in dependency order. Paste progress...Read full article on Community Announcements (Eviltek2099)Patch NotesOfficial
De-sync Patch
Single player solo should be unaffected. Multiplayer desync issues resolved.Read full article on Community Announcements (Eviltek2099)Patch NotesOfficial
New save game backup slots and dynamic panels.
Going forward, you'll be able to look back at previous saves and load them. Beware, loading a previous save becomes that saves anchor going forward. You can adjust the number of saves, even choosing unlimited, if you can spare the hard drive space. Dynamic panels allow you to bridge the gap between any two edges that are within 1.5 basic panels apart in distance. I'll get better at this, I swear.Read full article on Community Announcements (Eviltek2099)
