Game update

v0.2.8

Substrate: Emergence Alpha Playtest · published 5 months ago

All eventsPlayers around this dateRead on Steam

v0.2.8:
* Added crystal system: persistent environmental generators
* Balance tweaks:
- Reduced organelle maintenance cost
- Reduced movement cost by 10x (was previously 5x+ base maintenance cost)
- Increased collector attraction speed
- Plasmodium branches take damage from enzymes
- All cells now have some basal absorption. Higher basal absorption requires increased membrane permeability, resulting in increased vulnerability to damage
- Increased energy:cytosol base conversion ratio from 1:36 -> 1:48
- Increased particle sizes from ambient diffusion
* Added more environment sliders on culture creation:
- Ambient temperature slider
- Crystal options
- Basal substrate generation floor slider
* Contract system:
- Board no longer auto refills, refresh functions as a mulligan system (clear board and draw 4 fresh contracts)
- Active contracts can be abandoned (grants incur penalty)
- HUD shows tracked contracts instead of just the first active contract. Tracking can be enabled/disabled per active contract
* Rebuilt UI with a more consistent style:
- Replaced intro pop-ups with non-invasive hint cards
- Added playtest welcome panels
- Added copy diagnostics button under advanced settings panel
* Added new organelle: Endoplasmic reticulum. Secretes particles. Found in trophocytes
* Reworks:
- Lysocysts now fire packages of enzymes (previously called blastocysts)
- Reenabled amoeba with improved body shapes. Renamed amoeba -> Heterokaryon
- Improved pseudopodia, with the goal of bridging motile cell -> plasmodium evolutionary pathway
* Bug fixes:
- Improved strain classifier and collection consistency
- Removed plasmodia basal -> cytosol direct conversion path
- Fixed bug causing generalist cells to have no behavior outputs (ciliates, flagellates, etc)
- Other various bug fixes
* Renamed theoretical lab -> creative lab
* Added WIP autopopulate feature. Automatically adds cell to culture to maintain population floor
* Began reworking tutorial. Replaced most objectives with reactive hints
* Began highly WIP new rogue-like game mode "Lineage Control"
v0.2.8-1:
* Fixed bug blocking creative culture start
v0.2.8-2:
* Balance:
- Fixed issue blocking cells from self triggering mitosis
- Increased default temperature tolerance range
- Increased collector capture speed and radius
* Reduced creative lab cell spawner ranges due to high counts breaking things
* Performance improvements
v0.2.8-3:
* Balance:
- Increased basal absorption base rate for Plasmodia population support
- Decreased basal absorption for motile cells (compensates for above)
- Spontaneous gene additions now randomize parameters. Addition/deletion rates increased
* Environment now influences mutation bias
* Various improvements to lineage control mode
* Various bug fixes

In-game event14 Jun 2026v0.3.5: Final playtest update - moving to the demoHey everyone! First of all, thank you all for playtesting. Your feedback and suggestions have been great, and I am so grateful that so many people have been participating. This is going to be the last update for the playtest, as it will be closing on June 15th and moving to the demo. If you want to continue playing, you'll just have to switch over to the demo. It's the same build, just under a…Substrate: Emergence AGame update11 Jun 2026v0.3.4b-1 Hotfix* Fixed Sterilization failing to enableSubstrate: Emergence AGame update10 Jun 2026v0.3.4bv0.3.4b: * Cell population cap for upkeep raised 4x. A 4mm dish now has a cap of 80 cells before maintenance kicks in (n = dish size * 20) * All new culture options should unlock now upon tutorial completion * Pixelation filter no longer applies to UI. Removed UI pixelation option (leftover meme option) * Fixed acidic pH culture preset option dropping on some screen sizes
