Full Version History Timeline

Detailed Breakdown of Major Updates

Version 2.1.2 Hotfix (August 14, 2026)

• Cutscene Playback Fix: Resolved an issue where the atmospheric vessel insertion intro cutscene failed to play when launching Original mode within the Local menu.
• Steam Deck Video Sync: Enhanced video decoder synchronization on SteamOS to prevent brief audio stutter during inter-round transitions.

Version 2.1.1 Update (August 13, 2026)

• Custom Mode SHUFFLE: Added a dedicated SHUFFLE button within the Custom Playlist interface. When activated, the match engine randomly shuffles the order of your chosen minigames once the match starts, providing unpredictable sequencing while maintaining curated minigame lists.
• Local Achievement Registration Fix: Fixed a critical bug where Steam achievements failed to unlock for players participating in Local mode. All 15 Steam achievements now register identically across online and local play.
• Controller Disconnect Protection: Resolved a fatal crash that occurred if a wireless gamepad lost connection or ran out of battery during the local lobby ready-up phase.
• Localization Refinements: Corrected translation errors across multiple languages (German, Russian, Spanish, Portuguese, Japanese).
• The Filter Input Investigation: Developers logged community reports regarding occasional conveyor sorting lag in The Filter on specific hardware configurations, initiating targeted diagnostics.

Version 2.0.0 Milestone Update (August 12, 2026)

Version 2.0.0 stands as the largest content and structural overhaul in Machine Party’s release lifecycle, celebrating the milestone of surpassing 1,000,000 units sold on Steam:

• Native 4-Player Local Couch Play:
  • Added dedicated LOCAL title menu category supporting up to 4 simultaneous players on a single machine.
  • Compatible with up to 4 USB or Bluetooth gamepads (Xbox, PlayStation DualShock 4, DualSense), or a mixed setup consisting of 1 Keyboard and Mouse plus 3 gamepads.
  • Integrated persistent player naming and vessel cosmetic customization directly in the local lobby room.
  • Added a 5-second countdown timer once all local participants toggle Ready status.
• Dynamic Viewport and Camera Overhauls:
  • Duck Hunt: Features asymmetric split-screen (runners on the left viewport, sniper crosshair on the right viewport).
  • Inside Job: Implemented native split-screen views so survivors cannot screen-peek infection states.
  • The Filter: Implemented split viewports allowing each worker to monitor their private conveyor feeder.
  • Minefield: Deployed an adaptive proximity camera that dynamically zooms in and out based on the furthest spatial distance between surviving contestants.
  • Chisel Gauntlet: Dynamically switches between single-screen and split-screen viewports depending on jumbotron engagement.
  • Firearm Factory: Placed visible recipe ingredient indicators on every individual workbench so all players have equal sightlines.
• Balance Adjustments in Inside Job:
  • Buffed infected carrier movement speed to 1.15x baseline speed. Previously, infected players moved at 1.0x speed, making it nearly impossible to tag nimble survivors in open corridors before round timers expired.

Version 1.5.0 Content Update (August 4, 2026)

• Introduction of Arcade Mode: Added the streamlined 10-round Arcade playlist. The engine draws ten randomized minigames from the 15-game catalog and strips intro and outro cinematics, enabling non-stop competitive sprints. For full mode mechanics, see our Arcade Mode Guide.
• First Couch Play Teaser: Developer Mike Klubnika confirmed active development of local couch play for the upcoming Version 2.0 milestone.
• Lobby UI Polish: Cleaned up room code display fonts and added automated clipboard copying when clicking the Room Code widget.

Version 1.0.7 Hotfix (August 1, 2026)

• Day-2 P2P Socket Fixes: Resolved intermittent lobby timeout issues during peer-to-peer room code handshakes.
• Direct3D 12 Fallback Verification: Documented the official --rendering-driver d3d12 launch option for users experiencing Vulkan driver incompatibilities on legacy graphics cards.

Version Compatibility and Network Synchronization

Because Machine Party utilizes direct peer-to-peer socket negotiation between client machines, running mismatched game builds can prevent successful lobby connections:

1. Version Mismatch Errors: If a host is running Version 2.1.2 and an invited player is running Version 2.0.0, the lobby handshake may stall indefinitely or return an invalid room code notification.
2. Forcing Steam Updates: If you suspect a friend is running an outdated build:
   • In the Steam client, right-click Machine Party -> Properties -> Installed Files -> Verify integrity of game files.
   • This triggers an immediate check against Steam’s content delivery servers and downloads any missing delta patches.
3. Network Diagnostics: For lingering connection problems, packet drops, or firewall troubleshooting, refer to our detailed Room Code Protocol Guide.
