Charts
Each storefront's own chart, in its own country — the closest public signal to sales where none is published. A country missing from a list is one we don't collect there, not one where the game doesn't chart.
No United States chart position — it charts only in the markets below.

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.
Reviews, worldwide (the counter carries no country): 9/day in the week to Aug 24 → 12.43/day in the week after.
Too few observations to say whether a discount moves this store's chart at all: across the last 30 days Steam · Top Sellers · Poland has just 18 day-to-day chart moves that followed a price cut, against 2,498 that did not. We are publishing the count instead of a direction — 20 is the fewest we will draw a conclusion from, and price collection outside the United States began on 6 August 2026.
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
After hostilities have broken out in Central Europe, the race is on as a pressured US Navy escort force battle off Soviet bomber and submarine attacks on a perilous quest to reinforce NATO defenders in Europe. Meanwhile, in the Persian Gulf, the conflict between Iran and Iraq risks escalating into a larger confrontation between superpowers as both sides indiscriminately attack neutral merchant shipping. And in the Norwegian Sea, an outnumbered Soviet surface force challenges the might of a massive US Navy amphibious force bound for occupied Norway...
Brought to you by the lead designer of Cold Waters, Sea Power lets you control NATO and Warsaw Pact forces in a modern naval conflict. Whether it's gunning it out with Boghammars in a surface duel, fighting off aerial attackers armed with long-range missiles, or hunting for enemy submarines with aircraft and surface ships, advanced weaponry and sensors are at your disposal.
Can you successfully hide your forces while detecting and tracking theirs? It is up to you to play an advanced game of cat and mouse on the high seas, to seize the initiative and attack with the advantage of surprise on your side. And at all times, you have to observe rules of engagement and take care not to cause an unnecessary incident that could lead to escalation. After all, you cannot really be sure just who that radar contact at 30.000 feet is, can you?

太好玩了
非常好玩,就是太卡了,如果能优化就更好了
This is an awesome sea warfare simulation with all aspects of sea, air, sub. The graphics and attention to detail are mind blowing. It is a very detailed simulation, you will be controlling everything and will be very busy but in the best way. Still being in early access I can't wait to see what comes next. I am impressed every time there is an update. I would highly highly recommend

Sowas wie die dynamische Kampagne findet man heute viel zu selten. Leider aktuell nur 10 Missionen lang, aber mega gut.
A truly fantastic game for any Navy nerd. Seems intimidating at first, relatively steep learning curve. Becomes very rewarding quickly. Absolutely pushes naval knowledge and features an extensive encyclopedia about naval assets (Jane's Fighting Ships). One of the best aspects are the devs. They are very transparent, very active and very open to the community. Devs will regularly chat on the respective Reddit forum, take recommendations and help people master the game. I feel like updates and new content to the game accelerated recently, with their new Taskforce mode opening up amazing possibilities and allowing for a lot more content. The game really matures with every update, introducing amazing new features every time. The devs regularly add new assets and missions. The community is fantastic, very eager to push the limits of the game and introducing fantastic mods, features and tools to make the experience better. The price is steep, admittedly, however the game is on sale a couple of times per year. Worth it! Lots of features to increase realism are on the horizon. Sound updates, feature updates to allow for more depth... I wish they added more features that people know from Cold waters (Different sonar sounds for different vessels, Audio cues), however also keeping in mind that the role the player takes is different from both games, as in CW, the player commands one ship (submarine) and in SP, the player commands an entire strike group. The game is getting more optimized, however, you still should have a somewhat good system that is able to manage hundreds of individual assets (Ships, Missiles, Torpedos, Sonorbuys etc.)
好玩,不过游戏流程比较长,上手难度也高,优化不咋地,我的配置下有点卡,特别是齐射导弹的时候
优秀的游戏,潜力巨大,希望尽快出正式版!
Hard but a lot of fun and a lot of potential
Great game overall, but the specular aliasing pixel shimmering on zoomed-out ship models causes severe eyestrain. Fixing this subpixel flicker would make the game perfect!
Effectively a map game with some really nice visuals in the background. You'll spend most your time right-clicking through menus, reading through unit reference pages, and calculating measurements on the map. Then following your missiles in chase camera and watching your CIWS let yours ships get blown up Definitely scratches a super specific itch in terms of strategy games, and bonus points for workshop support. Since it's still in EA, some constructive feedback is below. It's mostly QoL to bridge the gap between "map and menu simulator" and an actual acessible video game, which I think can be easily done without changing the game's fundamental identity: Menu navigation gets annoying after a while. For example, aircrafts are 80% of the game, but to access the menu for deploying them, you have to: 1. Double click on the ship in the formation manager (skipping to right click only works for the unit you're currently-selected, in my experience) 2. Right click in the same spot 3. Navigate down to "Flight deck", hover over 4. Click "Toggle flight deck window". Flight deck window opens on the opposite side of the screen The formation manager has plenty of space for shortcut buttons, so it would be a nice to have. The tactical map is nice to look at, but you'll often have to go out of your way to find out critical information, which ends up interrupting the flow as you're doing it multiple times in a single engagement. Might be worth taking some inspiration from NEBULOUS: Fleet Command, where you can see your selected unit's radar/sonar ranges, maximum engagement range, and also seeing waypoint distance information. Bug-wise, the only big issue I've seen is with AI engagement, where your units will sometimes need encouragement to target/fire, even with weapons control set to "Free". This can sometimes annoying lead to unit losses if you're not paying attention. No issues running on Linux through Proton. Anchor Chain mod requires launch option WINEDLLOVERRIDES=winhttp=n,b %command% While £40 is a bit steep for a game still in EA, I think the amount of content justifies it. If on sale (occasionally goes on -20%), I would definitely buy if you're interested in naval simulator games.
