Improved peer reconnection with full state syncing so peer reconnection now works reliably. Disconnected players rejoin with their full game state restored. Sessions can be recovered using the lobby code.
Mycelium Conquest: Mitosis free co-op playtest is live — and your friends are invited. Think of Mycelium Conquest: Mitosis as a Friend's Pass: a free, co-op-only companion app to the full game. The playtest is open now and runs through July 8 . You own the full game, so you host — and your friends download it for free, join your session, and crash-land on the alien world of Xenoterris with you.…
This update improves co-op connectivity for players on cellular hotspots allowing hotspot players to connect directly to one another for a smoother, more responsive experience.
Changes: · Audio: sounds occasionally continued playing after quitting to main menu. · Visuals: ocean waves, camera shake, chat bubbles, resource overlays leaked across co-op sessions. · Network/chunks: lag from chunk load/unload thrash when players far apart; mid-session save load didn't disconnect old clients. · Player state: clients spawned dead/respawning after rejoin; wrong spawn positions…
Changes: · Tooltip fix — releasing consume mid-leap left the game thinking the player was still consuming a structure, permanently blocking structure hover tooltips, production controls, and resource node tooltips · Creature AI after player death — creatures stopped swarming corpses in co-op, disengaged from structures near dead players, and no longer get stuck in a siege→wander→chase loop; sin…
Hello Spores, Following up on my recent announcement about the new Co-Op Update, I want to share an important update on the future pricing of Mycelium Conquest. To reflect the substantial expansion in gameplay value and replayability that co-op brings, the base price of the game will increase from $9.99 to $14.99 USD on July 10th (regional pricing applies — your local price on the store page ma…
Changes: · Fixed a bug where hovering over buildings would stop showing status tooltips, requiring a full game restart to fix · Smoothed out creature movement so animals no longer appear to teleport or jitter around the map · Removed a misplaced "YOU (HOST)" label that was appearing above the player character in single-player mode · Fixed a crash that occurred when loading a co-op save and then…
Summary: Overhauled co-op networking with a hybrid peer-to-peer system that connects players directly whenever possible and falls back to a relay only when firewalls block it. Changes: · Co-op connections now try to connect players directly to each other first, only using a relay server as backup when direct connection isn't possible · Players behind difficult network setups (like apartment bui…
Summary: Co-op no longer routes gameplay through the hosted server. Players connect directly: same-WiFi is instant over the local network, and players across the internet go peer-to-peer with the server only handling lobby matchmaking. Loading a co-op save now takes the host to the lobby first with each player's slot reserved, Start locked until everyone is back, and the saved world restores st…
Summary: Fixed several internal systems were quietly accumulating leftover data from dead creatures, particles, and explored flora for the entire session, never cleaning up until a full restart. All three leak sources have now been patched, so frame rates should remain stable indefinitely during long sessions. This update is purely under-the-hood — no gameplay, balance, save files, or co-op beh…
Multiplayer Co-op Is here! Team up with up to 3 friends in the full campaign — shared resources, shared evolution, lobby codes, built-in voice chat and difficulty scaling with party size. Feature list: · Team up with up to 3 friends in the full campaign. · Shared resources — everyone contributes to the same pool. Build, research, and evolve together. · Host a game with a simple lobby code. · Vo…
Summary: The fix adds a safety net that re-requests Steam stats on the first game frame if the initial request during startup failed silently on some PCs (slow Steam startup, network lag, debug timing issues), preventing achievements from being permanently blocked due to stats never loading.
Summary: This update introduces multi-threaded simulation dispatch, allowing independent subsystems and creature updates to run in parallel across worker threads with automatic core detection and graceful fallback on low-end hardware. Several player-reported bugs were fixed: ESC now properly closes build menus before pausing, audio no longer screeches during mass attacks, and Steam achievements…
Summary: Fixes three player-reported issues: demo save achievements not carrying over to the full game, players dying during the evolution transformation cutscene, and deleted save files reappearing due to incomplete cloud sync removal. Changes: · Achievements earned in demo saves now unlock correctly when loaded in the full game · Player is invulnerable during evolution cutscene to prevent a b…
Summary: When a demo player bought the full game and loaded their save, stat-based achievements would never unlock because the resync happened before Steam stats were loaded. Changes: · Stats-based achievement resync now retries automatically once Steam is ready · Previously unlocked achievements are re-pushed to Steam when the retry completes
Summary: The hyphal network that grows across the map is now drawn much more efficiently. Instead of sending each thread to the GPU one at a time, all threads of the same type are bundled together and drawn in a single pass. This eliminates hundreds of redundant operations per frame, especially noticeable in late-game networks with many active roots. Changes: · All network threads are now drawn…
Summary: Fixed several visual and performance issues in the hyphal network and terrain systems. Network twig connections no longer clip under branch ribbons, large hyphal networks use edge-count-based LOD to maintain frame rate, loading a save with a different world seed no longer corrupts terrain textures or skips entity spawning, and evolution cutscene reveals avoid mid-animation disk I/O hit…
Summary: Fixed lag spikes during enemy waves and in water/swamp biomes by capping unbounded visual effects and skipping unnecessary render passes. Changes: · Capped frenzy trail and reduced spawn rate. · Lowered frenzy aura particle cap. · Added particle cap to the main particle system. · Water overlay pass now skips chunks without water tiles.
Summary: Reduces loading stutter and rendering overhead across the board, plus adds visual feedback when structures take damage. Changes: · Chunk loading pipeline streamlined. · Rendering optimized. · Minimap optimized. · Attack indicator pulses red at screen edge when structures are taking damage. · Chat bubble appears above player when bases are attacked.
Summary: When placing a structure, the game now highlights which existing structures and network edges would benefit from the placement. Transport boosts, chain bonuses, adjacency bonuses, turret range circles, and aura range circles are all shown in real time. The preview filters to only show actual benefits. Changes: · Green pulsing tint on affected structures and network edges during placeme…
Summary: The minimap was rebuilt to show where structures are and their count. Bottom structure HUD bubble now also show number of how many of a particular structure type has been built. Changes: · Tier-grouped structure count panels on minimap with build-palette styling · D-pad minimap button navigation with zoom in/out navigation · Strategic overlay blocks all non-minimap tooltips, HUD button…
Summary: A Steam stats API call during startup crashed the game on some machines. Additionally, achievements like creature consumption and structure placement weren't restored when loading a save from demo. Changes: · Fix Steam stats startup crash — guarded a Steam stats request during init that could fail or return invalid data on certain configurations, crashing the game at ~60% loading. · Re…
Summary: Steam overlay caused GPU crashes during loading on some drivers. Fixed by reducing loading screen render calls and deferring pause menu shader init.
Summary: Fixes a crash some players hit during the loading screen when launching through Steam, caused by the Steam overlay interacting with the loading render loop. Also corrects several structure descriptions, resource rates, and prerequisites that didn't match their actual behavior. Changes: · Fix Steam overlay GPU crash on loading screen — ShowLoadingStage rendered multiple frames per stage…
Summary: Steam Cloud sync was crashing during startup because it ran too early — before the main menu even appeared. The fix moves it to run only when the player actually opens their saves, keeping startup free of Steam Remote Storage calls. New players never trigger it at all. Changes: · Steam Cloud sync now runs only when you open your saves, not during startup · New players with no saves nev…
Changes: · Fixed an issue where the game would crash after the initial loading screen when launched through the Steam client. This was caused by a timing conflict between the Steam Overlay and the game's graphics initialization. · Improved fullscreen startup to use proper native desktop resolution, preventing resolution mismatches that could cause crashes on certain GPU and driver combinations.…
