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?

十分好玩的塞博斗蛐蛐海战游戏
i would like more involved missions that last for a day or so. I usually find myself playing the game during my work day and would like missions which allow me to hunt for a sub for days or have stuff like that where I may fly several missions but not find anything.
A great middle ground between approachability and detailed simulation, the recent updates of task force mode make your fleet composition and the ships you have really matter and makes it much more dynamic. Really impressed with some of the updates and direction of the game. Initially picked it up on early release and wasn't terribly impressed. That's all changed over the past couple years. Excited to see where it continues to go!
If you are a fan of strategic wargames, or Tom Clancy novels, this is a great game. In general: [list] [*]Gameplay is engaging and complex [*]Graphics are impressive and cinematic [*]Contains an immense amount of content [*]Performance is decent [*]Developers are passionate [*]Mission editor [*]Runs well through Proton [/list] The game experiences expected Early Access teething issues, but feels complete and refined in most areas. As of writing, there are a few substantial quirks: [list] [*]Lack of unit autonomy/Tedious controls (especially in aircraft) [*]Questionable performance in larger scenarios [*]Other unintuitive control schemes [/list] This game is well worth the 50 bucks.
Excellent game, and a early access that delivers more and more! Well done devs!
Set "Air Defense State" to "Weapons Free" with incoming aircraft and your ships will start shooting Harpoons at enemy ships instead of engaging incoming enemy aircraft.........."Air Defense State"........not weapons free.....
My Grandpa worked various roles in the Navy and marine corp from Korea to 9-11 and this reminds me of listening to him studying the various soviet systems as a child of the 80s and 90s. The cold war was very real in my house growing up near DC and this game is great for those who love naval battles in this age. Really well done for an Early Access game and it is well worth it too me in its current state.
Great Modern Warfare Sim. There are a ton of options you can do and make it as challenging as you want. Runs smooth on my 5060 with no issues. Its worth the money.
Un gran juego, muy recomendado, a pesar de que tiene bug, es súper jugable, lo están actualizando constantemente y mejorandolo mucho
