- Patch 2.0.4 - Level Editor Fixes + Easy Discord Sharing - 10 September 2026
If you encounter any bugs while playing, please report them to me on Discord! ------------------------------------------------------------------- Misc ChangesAdded a Discord Webhook that lets you post your Custom Level on Discord after publishing The "Share" button shows up after publish successReplaced the 2nd Event Level "Art Challenge: Siren" with "Fort Harvest"The Siren level feels too similar to the Turret Clam level, with the same kind of chaotic energy. This switch is to vary up the event more, and give you a more "normal"-feeling level that Darthen had spent a lot of effort on. ------------------------------------------------------------------- Bug FixesFixed a glitch where the game UI could confuse regular, semi-custom, and fully-custom level typesReported by alexniccah Fixed a glitch where the Anniversary Event notification does not go away after level completionReported by Vi…

Operation Octo turns 1 year old today! To celebrate, we are launching the 2.0 Major Update - Introducing the Level Editor! Create insane shenanigans and share them with your friends on the OO Steam Workshop! There are already lots of ultra-creative levels created by our beta testers over the past week.

- Patch 1.6.3 - Fixed Leviathan Battery Glitch - 9 April 2026
I said last night's patch was gonna be the last one before the 2.0 update. Of course another new (and totally game-breaking) bug got discovered 😬 I'm not gonna say this will be the last patch before the major update, so I don't jynx it 😏 If you encounter any bugs while playing, please report them to me on Discord! ------------------------------------------------------------------- Bug FixesFixed a glitch where Leviathan Battery cannot be picked up by OdinReported by Studimus ------------------------------------------------------------------- Misc ChangesAdded Spanish, Romanian, Czech, Russian localizations for the April Fools eventI kept Everywhere Siren a secret even to the translators. The translators immediately labored away at the new texts after the update dropped, and how did I repay them? I forgot to download their translations before making the last patch! SooorrrryyyyyyyyI wa…
- Patch 1.6.2 - Custom Level Issue Fixes - 9 April 2026
More bugs surfaced surrounding custom levels - This should be the last round of bug fixes before the 2.0 major update (for the Level Editor) in a month! If you encounter any bugs while playing, please report them to me on Discord! ------------------------------------------------------------------- Balance ChangesWhile chasing a bandanaed / charmed skeleton, Spiky Urchin now tries to pathfind to the tile ahead of the enemyThis allows Urchin more time to stay still & attack a banded skele, before the skele walks out of range and forces the Urchin to start rolling again in pursuit. ------------------------------------------------------------------- Bug FixesFix attempt for a glitch where custom levels sometimes fail to generate Level Boundaries if it is the first level scene you entered after game launchReported by BullsiFixed a glitch where insta-turret achievements that require trackers,…
- Patch 1.6.1 - Special Event Level turning into the Void - 1 April 2026
Quick patch because apparently, this could happen: I was too good to ever fail at my own levels, and hence could never have found out about this 😎I'm surprised the new custom level loading system has given no issues other than this one - Enjoy the event y'all!
- Introducing Turret Fusion! (April Fools 2026) - 1 April 2026
Limited Time Event!(Edit from the future: Yes, this was an April Fools joke) Be among the first to try out our brand new gimmick - Turret Fusion! Everybody loves fusions. Fusions are cool as heck. What do you get when you combine an Everywhere Eel with a Siren? Starring Creeps20 as his iconic role of maculate evanescence! Play the limited-time event now, featuring 3 new custom levels! (You can access events after you've beaten Level 1-10) (I'll make a past event archive eventually... But given how incredibly "efficient" I am, the archive probably won't come out within the next half a year. You should play the event now. Don't miss it.) (Note: The new levels could be hard - Probably don't play them with "Speedrun Mode" still on) If you encounter any bugs while playing, please report them to me on Discord! ------------------------------------------------------------------- Balance Changes…
- Patch 1.5.1 - Axolotl Changes & Fixes - 17 March 2026
Quick round of fixes. Don't mind the new "CustomLevel" folder in your save location - The Level Editor is finally WIP 😬 If you encounter any bugs while playing, please report them to me on Discord! ------------------------------------------------------------------- Balance Changes Axe-o-lotl initial gadget cooldown increased from 30s to 50sAxe-o-lotl is over-shadowing Spiky Urchin as the early game gadget - I don't want Urchin to lose its primary use case. Reverted all previous Boomerang Skeleton / Disorientation nerfs / reworksBoomerang's inflicted Disorientation duration reduced from 5.5s to 4sOdin has 3 seconds of immunity from Disorientation upon recoveryWhile already disoriented, getting hit by a boomerang again would no longer extend the remaining Disorientation duration While disoriented, a "tick" sound effect now plays every second with increasing pitch to help keep track of wh…
- New Gadget - Axe-o-lotl! - 9 March 2026
New Gadget - Axe-o-lotl Based on ideas by Silviu Offtopic (The Romanian OO translator), the Axolotl gadget is ready for her rampage! Axe-o-lotl hops onto Dr. Odin, then swings her axe-shaped gills around, slashing the skeletons around you in four different directions! Axe-o-lotl will finally provide a melee, AoE gadget option. She can absolutely decimate hordes of skeletons, but this requires you to run head on into danger & dance around to aim each of her attacks! (Yes, I voiced Axolotl myself. No, the voice recording was not edited at all!)(Yes, Axe-o-lotl was meant to sound like Jack De Sena) Axe-o-lotl is unlocked after Toxic Wasteland Level 2-11! If you encounter any bugs while playing, please report them to me on Discord! ------------------------------------------------------------------- Balance ChangesPotion Factory can no longer deploy while you're already tossing a turret onto…
- Patch 1.4.1 - Spanish Localization is here! - 3 March 2026
If you encounter any bugs while playing, please report them to me on Discord! ------------------------------------------------------------------- Spanish Localization! Special thanks to Alejandro Pulgar-Vidal for translating Operation Octo into Spanish (Latin America)! Alejandro speedran the translations. He finished everything in like, idk, 3 days? Like the based Romanian version, this is also a localization that takes a lot of creative liberty with the Turret / Skeleton stories, and has abundant lores of its own. It's worth checking out even if you don't speak Spanish ;) ------------------------------------------------------------------- Balance Changes Bolt Eel now has an illumination radius of 3.5Hollow Bolt Eel now has an illumination radius of 5Mutant Bolt Eel now has an illumination radius of 6.5Virty thought Eels could always produce light all along. This made me realize that Ee…
- Art Contest Results & Steam Leaderboards for Speedrun Mode - 20 February 2026
Buckle up, Turbo - This is a pretty big round of updates, with lots of new things to play around with, and even Steam Leaderboards to compete in! If you encounter any bugs while playing, please report them to me on Discord! ------------------------------------------------------------------- Art Contest Results - Heal Snail Upgrades Many moons ago, the Discord server began a lengthy discussion about possible ideas for Heal Snail's elixir forms. This is why an Art Contest happened, so that Frosty & Hollow snails are fully designed by the community! (Next thing you know, Imma get pressured into making Hollow Mussel smh) 🔮 Hollow SnailWhen a nearby turret dies, spawn explosive mines on all surrounding tiles that drain enemy health upon explosion Idea by Creeps20 Art Contest winning entries: Lampshade Snail by LameGamerTimeBony Snail by PuyoChild 🧊 Frosty SnailConverts all connecting mucus…

- The Creeps20 Turret - Everywhere Eel - 23 December 2025
New Turret - Everywhere Eel! Behold the Garden Eel turret designed by the PvZ YouTuber Creeps20! (Yes, Creeps voice acted for it too) Everywhere Eels randomly teleport themselves all over the map, and shoot bubbles at skeletons. They get scared away when approached by either you or skeletons - Strategically relocate those Eels to move them to where skeletons are! Before people ask, you can in fact upgrade Everywhere Eels. You'll just have to figure out how to get close enough without scaring them away ;) Unlock Everywhere Eel now inside the Toxic Wasteland store! (Bought for 5 Rubies after you've beaten Level 2-10) If you encounter any bugs while playing, please report them to me on Discord! ------------------------------------------------------------------- Balance ChangesMutant Clam now costs 20 pearls to upgrade Mutant Clam simply provides too much value over the course of a long lev…
- Patch 1.2.1 - Ukrainian Localization is here! - 20 November 2025
Ukrainian LocalizationOperation Octo has been translated into Ukrainian by Lavauk! Pretty good timing - Matches the new Argonaut's color scheme ;) If you encounter any bugs while playing, please report them to me on Discord! ------------------------------------------------------------------- Balance ChangesInside Level 2-5 "Clam Farm", only pearls that were initially produced by the player (before getting consumed by Argonaut) will count towards the pearl production goal after the Argonaut refunds those pearls This is to prevent Argonaut spam from becoming the ultimate Clam Farm speedrun strat; Note that due to coding limitations, new Argonauts spawned by Mutant Argonaut will not remember if their stored pearls were produced by the player.Frosty Sniper Turtle now has passive regen This is to further incentivize using Frosty Turtle as a frontline tank, differentiate this upgrade from the…
- Argonaut & The Soundtrack Release - 15 November 2025
The Soundtrack is Here!The 🎵Operation Octo OST🎶 is finally available for streaming / purchase! 🔵 You can buy the OST on Steam, which contains high-quality & loopable versions of each track for download! (ft. Volcanic Ridge theme sneak peek?!) 🔴 Click here for the YouTube playlist 🟢 (The Spotify playlist is currently incomplete, due to distributor delays) Think of the Steam soundtrack as a tip jar for me, if you liked the game :) New Music for Special Game Modes Daniel Teles has composed some (insanely good) new tracks for Mini-Game Levels & Ultimate Battles (Turret Clam Levels)! I gave Daniel the "Crimson Front soundtrack" as reference for the Ultimate Battle, hence the track has the "jazz swing big band vibe" - Go check it out inside the game or the OST now! New Turret - Argonaut Welcome the most complex / unique attacking turret yet - The Argonaut! (i.e. Paper Nautilus) Argonaut…
- Frogfish & Romanian Localization! - 26 October 2025
Welcome to the first content update for OO! Romanian LocalizationOO has been translated into Romanian by Silviu Offtopic - The creator of PvZ Romania! I gave Silviu a lot of creative liberty with the translations, so this Romanian localization is a heck of an expansion to the OO lore ;) (Yes, whatever Silviu wrote is to be considered canon)------------------------------------------------------------------- New Gadget - FrogfishTired of always bringing a collector to every battle? Wanna free up that 6th turret slot for something else? Well, good news: Frogfish is here to end Pleco's career for good! Frogfish is both a collector AND a pearl producer! What's more? He is a free gadget that does not occupy any space in your deck! Frogfish uses his tongue to collect pickups across a massive area, as long as he has direct line of sight. If you manage to dodge his tongue so that the pearls get…
- Patch 1.0.6 - Buncha Bug Fixes - 3 October 2025
I'm moving, so no new turrets yet... But expect them soon! The OST release has also been delayed due to the review process - Stay tuned... If you encounter any bugs while playing, please report them to me on Discord! ------------------------------------------------------------------- Balance Changes Hermit Holster's wake-up range increased from 3.3 to 4 Hollow Hermit's wake-up range increased from 3.3 to 5.5 Hermit has been an incredibly powerful, yet unpopular turret, due to how much time they often stay asleep for. Making it easier for Odin to wake them up (even across a lake) should help things. ------------------------------------------------------------------- Bug Fixes Fixed a glitch where certain achievements cannot unlock inside Graveyard Reported by Something Fixed a glitch where Leviathan disappears from the Graveyard Reported by Darthen Fixed a glitch where on slower computer…
- Patch 1.0.5 - Czech Localization is here! - 25 September 2025
The Czech localization is live! Special thanks to our translators Citrus & KakaoDei for their hard work, finishing this full localization only 2 weeks after the game's launch! If you encounter any bugs while playing, please report them to me on Discord! ------------------------------------------------------------------- Balance Changes Disorientation status effect duration can no longer be reduced to below 1 second by Odin taking damage Odin now gains immunity to disorientation for 1.5 seconds after recovering from a previous disorientation Within 5 seconds after recovering from disorientation, if Odin becomes disoriented again, the newly applied disoriention duration would be shorter than usual The previous round of disorientation nerfs allowed the status effect to wear off faster whenever Odin takes damage. This resulted in sudden recoveries that some players found to be even more dis…
- Patch 1.0.4 - Stun Lock Fix & Disorientation Nerf - 19 September 2025
A quick patch that addresses some pain points among the new enemies. More significant level balancings & bug fixes coming soon! If you encounter any bugs while playing, please report them to me on Discord! ------------------------------------------------------------------- Balance Changes If Odin gets repeatedly stunned, his stun duration is cut short by increasing amounts each time I always thought of stun-locking as a rare & funny thing, but raged-up Captain Phantoms have claimed too many octopus lives, and made Level 3-14 nightmarish for those who don't possess the necessary techniques. Being stun-locked for an extended period of time doesn't feel fair to players either, so I am now preventing it from occurring. A raged Captain should only get 2 hits on you now, if you make an attempt to run away! When Odin is hit by a Boomerang while already disoriented, the new Boomerang hit will n…
- Patch 1.0.3 - Operation Octo - 16 September 2025
Time for the post-release Patch :D (Full disclosure: It normally takes me a month to make a boss fight, but I had to make the Twilight Zone boss in 3 days. He needs A LOT of tweaking right now, and I intend to majorly rework him in the next few days!) If you encounter any bugs while playing, please report them to me on Discord! ------------------------------------------------------------------- Bug Fixes (I am aware of several other issues you guys have reported - I will aim to fix them soon!) Gameplay Bugs Fixed a glitch where Imitation Crab cannot transform into a Bubble Parrot Reported by Lavauk Fixed a glitch where Watchdog's cost isn't capped at 60 pearls Achievement Bugs "Salty Seadog" achievement can no longer be acquired by not exiting a finished level Fixed a glitch where "Salty Seadog" achievement fails to unlock Fixed a glitch where "Archeologist" achievement does not unlock…
