Changelog

What's new in Petriarch, newest first.

2.0.4

2026-07-26sim 32 · config 21
  • The game now stays smooth when a lot of players are online at once. If it ever gets too busy, you will see a friendly wait screen for a moment instead of errors.

2.0.3

2026-07-25sim 32 · config 21
  • The tip text on the unlock and progression screens is bigger and clearer now, so it is easier to read at a glance.

2.0.2

2026-07-25sim 32 · config 21
  • New players now get a short intro screen first that lays out the whole climb, the ranks you unlock as you go (evolve, strains, armor, boons, then the ranked ladder) and how you earn rank: at the end of each full run, and the more rounds you win, the more you climb.
  • Fixed an armor card (Chitin Plate) that could show up in your shop before you had unlocked armor. It now waits until armor is unlocked.

2.0.1

2026-07-24sim 32 · config 21
  • Opponents that are bots now correctly show the (bot) tag again. And when a real player is near your rating, you get matched with them ahead of a bot, so you run into more humans as the community grows.
  • Behind the scenes, finished runs no longer hold onto a big leftover battle trace, so saved runs take far less space.

2.0.0

2026-07-24sim 32 · config 21
  • Reordering the mods on a generator is drag-and-drop now: the other mods slide out of the way live as you drag, so you see the final layout before you let go, and it works right on phones.
  • Mods and strains that hit more than one enemy now read as "+1 target" so it is clear how they stack, and they can stack a little higher than before.
  • Your boons show on the post-battle stats screen now, for both sides, and a generator's detail shows more of what is going on: splash radius, heal targets, attack targets, and how many extra split children you make.
  • The unlock screens got a polish pass, and reaching the ranked ladder is a bigger moment now, with a note on what to expect as you climb.
  • On desktop the main button stays put while a long screen scrolls.

1.12.0

2026-07-23sim 31 · config 21
  • Every card now has its own icon, colored and shaped by what it does, so you can read your whole board at a glance. Poison reads violet, healing green, armor steel, and so on, and each kind of card (mod, strain, boon, colony, action) has its own frame.
  • Ranked runs now go 14 rounds instead of 12, so a build that is coming together gets a couple more rounds to pay off. Progression runs stay at 12.
  • Boons got a pass: the few strongest ones now cost a little of that round's biomass, your held boons show up in the draft alongside your colony and actions, and the pick screen has icons and a line of flavor now.
  • Menders that stack heal-target boosts (a strain, a boon, an evolve) now heal one more target each, with no cap, so a healer build can really roll.
  • Reflect now shows on a cell's detail, combined across thorns and every reflect source.

1.11.0

2026-07-22sim 30 · config 21
  • A big batch of new strains to open with, including two Generalists that build three different roles at once, a stinger that hits two enemies per shot, and fresh takes on poison, walls, and brood.
  • Evolve got a real pass: every specialization now has a capstone evolve to build toward, and some fusions buff your whole colony, not just one cell.
  • Armor rework: it now clearly protects your generator, one new plate slowly regrows between hits, shrapnel actually hurts when it goes off, and there are new mods that make your generator tougher. Reflecting a killing blow off a wall now counts as that wall's kill.
  • Clearer wording throughout on how poison and strain perks read.

1.10.3

2026-07-13sim 11 · config 20
  • Clearer after a battle: the button to keep going now says "Next round" instead of "Shop," and the first round spells out that a run is many rounds. No more wondering how to continue.

1.10.2

2026-07-13sim 11 · config 20
  • After the last round, you can start a new run right from the results screen. No more hunting for how to play again.

1.10.1

2026-07-12sim 11 · config 20
  • Shared run and battle links now show a preview card (title and description) when you post them in a chat or on social apps, instead of a blank link.

1.10.0

2026-07-12sim 11 · config 20
  • Shared runs show a lot more now. Each round tells you how it actually ended: Slaughter (you did not lose a single generator and none were even scratched), Wipeout (all your generators survived), Clutch (you won but lost one or two), Fatigue (the fight ground into the attrition phase), or Tiebreak (it went to the time limit and was decided on health).
  • You can click any round in a shared run to watch that exact battle, not just the final one.
  • New games record who you fought (name and rating at the time), so replays show your real opponent instead of just "Opponent." Older battles never stored this, so they still say Opponent.

1.9.3

2026-07-12sim 11 · config 20
  • Fixed short run share links (/run/...). They were bouncing to a page that said the run was invalid or corrupted. Now they open the shared run as intended.

1.9.2

2026-07-12sim 11 · config 20
  • You can now turn the slow-motion battle finish on or off in the replay settings (the gear icon). It is on by default.

1.9.1

2026-07-12sim 11 · config 20
  • Battle replays: the slow-motion finish is now scaled to the length of the fight, so short, quick battles no longer play almost entirely in slow motion.

1.9.0

2026-07-12sim 11 · config 20
  • Move-speed mods are out for now. Hunters were already at the top move speed, so the Fast mod did nothing on them, and move speed turned out to matter little in fights. Pack Instinct is now a real Hunter payoff (+3 attack and +3 health), and the Predator strain gives Hunters more attack instead of a speed boost that was doing nothing.
  • A stat that is already maxed out now shows MAX, and a mod that would not change a generator is called out so you do not waste it.

1.8.5

2026-07-12sim 11 · config 19
  • Lobber cells on the battle board now show as a dot inside a ring, matching their generator glyph.

1.8.4

2026-07-12sim 11 · config 19
  • Small tutorial fixes.

1.8.3

2026-07-12sim 11 · config 19
  • The new-player tutorial now uses the real game screens, so what you learn matches the game exactly.

1.8.2

2026-07-12sim 11 · config 19
  • In the tutorial, placing a card now matches the real game: tap a card to pick it up, then tap a generator to place it on.

1.8.1

2026-07-12sim 11 · config 19
  • The new-player tutorial now uses biomass like the real game, so you buy cards from the shop and they leave your hand. The Play the tutorial button on the sign-in screen is easier to spot too.

1.8.0

2026-07-12sim 11 · config 19
  • New players can now try a quick guided tutorial before signing in. Learn the basics, win a few rounds, then sign in to play for real.

1.7.3

2026-07-12sim 11 · config 19
  • Small under-the-hood improvements. No gameplay changes.

1.7.2

2026-07-12sim 11 · config 19
  • Bot opponents are now labeled "(bot)" so you know who you are up against while the community grows.
  • Added a "Send feedback" option in the menu. Tell me what is working and what is not.
  • Buttons and generator tiles are bigger and easier to tap on phones.

1.7.1

2026-07-12sim 11 · config 19
  • When a game update ends a run that was in progress, you now get a clear notice and a fresh start instead of reloading twice. No rating penalty when that happens.

1.7.0

2026-07-11sim 11 · config 19
  • Three new strains: Barrage opens with a long-range Lobber, Pyre surges and poisons as your generators fall, and Renewal slowly heals its cells.
  • Every role now has a tier-3 capstone. New ones for Splitters, Menders, Lobbers, and Stingers.
  • Two new modifiers: Bramble reflects damage to melee attackers, and Decoy taunts enemies onto a cell you pick.
  • New colony cards for Lobber and Stinger builds.

1.6.0

2026-07-10sim 11 · config 18
  • Split cells now scale with their parent's upgrades, so buffing a Splitter carries through to the cells it spawns.
  • Fixed shared run links (/run/...) opening the home page instead of the run.
  • The draft shop now shows your available biomass right above the reroll cost.
  • End of round: the opponent's colony and its stats are easier to read.

1.5.1

2026-07-10sim 11 · config 17
  • Small under-the-hood improvements. No gameplay changes.

1.5.0

2026-07-10sim 11 · config 17
  • Pick your own username. The first time you sign in you now choose a name, and that is what shows on the ladder instead of your Google name.

1.4.3

2026-07-09sim 11 · config 17
  • Tidied up card and strain descriptions so they read cleaner.
  • Fixed the website on phones: the header now has a proper menu instead of wrapping links, and the text no longer runs to the screen edge.

1.4.2

2026-07-09sim 11 · config 17
  • Small under-the-hood improvements. No gameplay changes.
