Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.29/day in the week to Sep 11 → 0/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Honestly, after giving this a real honest try I hate to be the person to write the first negative review. After giving this game 4 hours of my time I have found this game has incurred the worst feeling I can have towards a game. This game annoys me. I will try to explain why. I want to start off with the positives. I think this game has a charming art style. Everything is cute or quirky in some way, and that is the end of it for me. Now for the bulk of this review, the negatives. I going to start with what I find to be the most offensive aspects and then move my way down to nitpicks as not everyone wants to read a long review. The towers conveyer, is terrible. You know how in plant vs zombies how your towers have a cooldown? Well Operation Octo throws away this type of system by instead putting your 6 towers on a conveyer that only gives you access to 3 at one time. You must place a tower down to get access to the next. You have to burn through the conveyer to get to towers you need sometimes, which just makes gameplay needlessly chaotic. Not only are you running around most of the time due to your tiny sphere on influence around your character you also have to keep track of the conveyer at all times. Map design causes restrictive loadouts. The maps in this game, are designed in such a way that enemies have the advantage. You are surrounded and there are many enemy types that can bypass walls, either by flying, swimming or firing over obstacles. Then there is the issue that there is very little indication of where enemies will come from once the full map is surrounded by enemies ships. There is no UI element like maybe a flag slowly raising on each ship to give you an idea of where to plan ahead with defenses. This causes you to just take simple loadouts that just deal with the specific enemies in the level. It's very rock, paper, scissors. It just makes the gameplay fairly stale as you're not doing anything new. I see an enemy, I need to solve the problem it causes, and if I don't I will struggle. Enemy Spawns are very random. This is most noticeable at the beginning of a level. Lets say you start a level and enemies first spawn in the south but you built up things in the north by mistake. You can restart the level and build in the south, the enemies will then come from the north. It's random you have to wait and react to every enemy wave as they come. Personally I don't like that. The Dev's obsession with keeping the camera super close to the character. In a game that requires me to react to enemies spawns the game sure does hate me being able to actually see anything. Want to place a tower, camera zooms in, get hit with paint, camera zooms in. It's just a needless irritation. I just have to constantly zoom back out because the dev says "I want you to have to scout things out actively". However, the game itself is hampered by this odd quirk. The Economy is not great either. There are quite a few ways to gain pearls in the game, waiting, using specific towers, and killing enemies. However if you want a tower that does anything that is remotely special like maybe shoots over a wall or shoots more than one projectile you will be forking over 70-80 pearls. But due to the conveyer you will be forced to spend more to get to these towers. I can't tell you how many times I had to just throw down a couple of towers I didn't specifically need that second so I could fix a problem. Due to the randomness of enemy placement I can't just place a mortar tower in advance to help with that issue, plus they cost so much you run into the issue of not having enough defenses to hold off the early waves. The game is grating on the ears. The combination of random boney clatters, damage noises, towers exploding, and music is just so unenjoyable. What's worse is you're stuck with them, as the game lacks a functional UI to allow you to just turn everything off and play with some music on. You'll be missing vital info without the awful soundscape. The game telling me I'm playing wrong There are some actions in game that will constantly cause a tutorial message to pop up and say "HEY DON'T DO THAT PLAY HOW I WANT YOU TO!" I am being a little hyperbolic of course but it does say things like "Bring a pistol shrimp its not in your loadout". Hey what if my strategy involves using the many other damage dealing towers in your game? Don't tell me what to do. The culmination of many of the game elements make this game very chaotic and not something I want out of a tower defense game. The character controlled tower defense style has been done and done well in fact. Orcs Must Die is a good example. This game lacks too much information, is too random and is too quickly paced to allow you to make any meaningful tactical decisions. You often just end up running around putting out fires rather than creating a solid foundation to defend from. Now is this a hard game you ask? No, it is not, a kid can stumble through it and probably be giddy as they do. Does this game cause me low grade irritation due to a myriad of design choices? Yes. I see what the dev was trying to do, but they put some thing into the pot I am allergic to. I wish I could enjoy this gumbo but it makes my skin itch and eyes water.

This is a fast-paced tower defense that keeps introducing unique turrets, enemies, and upgrades that have tons of synergies to explore. I'm often getting by on the skin of my teeth in later levels, but it's also not too hard to control a recovery. Worth a play if you loved tower defenses back in the day, but want to play on a bigger, more chaotic battlefield.
Operation octo is a fantastic Game, theres Numerous of Turrets as you progress through the game, that add to the strategy of the game, with a Plethora of Unique Enemys. And new strategys that you utilize to survive in the Harsh Underwater Climates. and some really Unique gameplay that is quite engaging! And also Enjoyable! Very responsive Gameplay. its Smooth, (Like Butter in a Frying pan) like sargent Roebuck would say: "Quick and Clean" and the Graphics are Stupendous and Charming! and get this: Operation Octo was made Single, Solo, Dev :o and i get it for Six Dollars!!! :O If i had to compare it to anything. Plants vs Zombies Comes to mind, if PVZ toke more then 2 Brain Cells to play! its Insult- wait no, Very insulting to even compare PVZ to OO. its far Superior in every way, and your gonna have to Think to play this Game!! (and i Couldn't say that about PVZ!!) its a great game, i've enjoyed playing it! Looking forward to future Updates! According to my brother, he's already updated the game 5 times since release!! If you wanna a game, that doesn't treat you like a toddler *Cough Cough Triple A* I Recommend tring out This game! 9/10
Underrated gem that has pretty much everything I liked about Plants vs. Zombies, while still being a completely different and original concept. From the charming artstyle, to the turret and enemy variety, to the simple yet chaotic gameplay, to the little details and interactions you don't notice at first glance, to the silly shenanigans you can get away with if you play well enough, it has pretty much everything I'd want out of it. Despite still being in development, the 3 worlds that are already released, alongside the constant content updates, give out way more replayability than you'd expect. There's a lot of achievements that propose fun little challenges, there's a whole integrated speedrun mode with leaderboards, and you can also make your own challenges or check out the ones posted by the community on the Discord server. Admittedly, it is quite a bit more challenging than Plants vs. Zombies, both in terms of difficulty and mechanics, though it does offer a few settings to make the game easier if you [i] really [/i] need to (or make it harder, if you're having the opposite problem). If you're still doubting whether to buy the game or not, the demo lets you access all of the first world's content for free, and all of your progress in the demo will be transferred to the main game once you buy it.
Very fun game. The core gameplay is top-notch. Nothing is left unclear to the player; tutorials are well made and natural. At times the gameplay feels hectic, but every part can be mastered by the one who is committed to it. My one worry is that the addition of new towers and areas may end up bloating the game, but it will still be fun either way. The music and graphics are really cool and I'm generally a fan of ocean aesthetics; however, the sound design has some flaws and may bother some players. P.S.: If you are a pro, turn on the two "no-healing" challenge settings in the options. P.P.S.: If you are not a pro, but are annoyed by barely hanging on til the end of a level...also do that. :)
The oceanic insanity version of PvZ, Operation Octo is a tower defense mixed with bullet hell. The game may not be fully finished but with some extra content and challenges in the discord server, there is some replayability to the game! The dev also has almost monthly updates to the game so the game's always something new to strategize with!
The more you play Operation Octo, the more brilliant it gets. This is the best kind of "Fine, I'll do it myself" type of game, lemme explain. Pros: + Charming, simple art style that gets across what every fish turret / enemy does with one look. Very accessible for younger gamers. + It's the most constantly "on the move" mobile tower defense game ever. You are always moving, and both you as the player and the resources you protect matter. This makes for a very exciting gameplay loop. + It took what worked about the genre greats before and expanded on it. You have multiple types of upgrades for turrets, you have unique level designs and new challenges consistently, and it challenges even experienced gamers over time. + The sushi belt and elixir limitations breed creativity. You don't need to employ one solution to solve a certain type of enemy in a given level, you have multiple options that you unlock over time. Cons: - The music is just okay, nothing fantastic but it does the job. - It's still doesn't have all the content the dev has planned for it, even at a 1.0 launch. It's a good amount for a very low price, but it's not really a "finished" game yet. 9/10, one of the most pleasant surprises I've seen on this platform, for sure.
need a crab trap to hold me irl
Fun game! Might write a longer review later idk.
Operation Octo is one of the most chaotic Tower Defense games I have ever played, and I love it for that! Constantly, there will be something to look out for, whether it's collecting things, placing down and upgrading your towers, cycling through your belt to get to the tower you actually need, or praying to god you survive at the end of the level. Sometimes, the chaos is overwhelming even, with bandana and ranged skeletons relentlessly harassing you or nasty special skeletons making quick work of your defenses and getting to your CLAMs. But no matter how bad it may seem (or sound, iykyk), you can overcome it if you keep your calm and and pay attention to your surroundings.
