Prices
The United States storefront in every case, so this compares stores and not countries.
Discounts
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.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 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.
About

1878. The familiar world disappeared beneath the waters, leaving survivors adrift in the vast ocean. Humanity's only salvation was the «Isla Muvimi», floating islands that became centers of trade, war and survival.
Your mobile island is a living machine that requires resources. Collect artifacts, earn money in dangerous forays and invest it in upgrading your buildings.
In this story, inspired by the atmosphere of "Waterworld" starring Kevin Costner, you embark on a search for your missing father. He vanished, leaving only clues leading to a mythical continent. And only your «Isla Movie» can help you reach him. Grow your mobile island to discover the most remote regions and change the fate of the sunken world.

Heart of the Island: Build, manage, and upgrade your floating base. Each building is a step toward technological superiority and new capabilities.
Steampunk arsenal: Man turrets to repel attacks, command fighter jets or don a heavy diving suit for dangerous dives to the ocean floor.
A vibrant economy and progression: Complete missions and discover rare resources to transform your island into an impenetrable fortress.
Mysteries of the deep sea: From surface battles to uncovering the secrets of sunken cities, your capabilities grow with experience and equipment.
Are you ready to face the ocean? Add Sea Walker Saga to your wishlist and begin your saga!

最初は普通の探索ゲームかと思ったけど、島がそのまま世界を移動していくのを見て一気に好きになった😂 探索、建築、アップグレード、戦闘、乗り物がちゃんと一つの冒険につながってる感じがいい。キャラクターも可愛いし、次の無料アップデート待ってます。
I hate this game. Not because it’s bad. Because I finished all the content I wanted to play and now I have to WAIT 😭 Sea Walker Saga surprised me a lot. I expected something pretty simple but the moving island concept is actually brilliant. Your base basically travels together with you and because you can build and improve everything there you start getting attached to this place. It’s YOUR island. Your buildings. Your upgrades. Your little travelling home. And visually it looks beautiful. Especially when you arrive somewhere new and the environment completely changes around you. There are obviously Early Access problems. Some mechanics could use more polish, balancing probably needs work, and there simply isn’t enough content yet. But honestly this is normal for EA and I knew what I was buying.

巨大な島そのものが動いていくっていう発想がめちゃくちゃ面白い。景色も綺麗で、島を少しずつ強化して自分の拠点にしていくのが楽しかった。
Sinceramente eu não esperava que a parte que eu mais ia gostar nesse jogo fossem os combates com veículos. As batalhas com drones são MUITO divertidas. o controle responde super bem, você consegue se movimentar rápido, mirar, desviar e entrar nas brigas sem aquela sensação pesada que muitos jogos têm. Depois que peguei o jeito eu simplesmente queria mais e mais combate 😂 E as partes com avião também foram uma surpresa enorme pra mim. Voar, atacar os inimigos, fazer manobras e depois voltar pra ilha ficou muito mais divertido do que eu imaginava. Mas principalmente: a mecânica de tiro funciona muito bem. As armas são gostosas de usar, as torres são legais e eu gostei demais da sensação quando começa uma batalha grande e tem tiro vindo de todo lado. Só tenho uma reclamação: POR QUE VOCÊS DEIXARAM A GENTE USAR O BATISCAFO TÃO POUCO??? 😭😭 A parte de explorar embaixo d’água foi uma das coisas que mais me deixou curioso e acabou muito rápido. Eu queria poder descer mais fundo, explorar lugares diferentes, procurar coisas no fundo do mar, talvez lutar lá embaixo também. por favor no próximo update dêem mais tempo com ele!!! No geral eu acho que o jogo precisa de mais expedições. Quero sair mais da ilha, pegar veículos diferentes, voar, dirigir, mergulhar, lutar e descobrir lugares novos. A base e a ilha são legais, mas agora que vocês me deram esses brinquedos eu QUERO USAR ELES 😂
