“Game is a solid sandbox, good starting point but still no Mod Support first of all and secondly has been practically abandoned pretty soon. They put down the basics but forgot to finish it. Anything good you can have…”
“Fun game, there is a learning curve but that curve isnt that bad if your interested and are willing to put in the effort.”
“Very good graphics. Ease of controls. Ability to tailor your forces within historical limits. Tense gameplay especially dealing with sub and air attacks, requires some tactical thought. The strategic elements again adds…”

“Zero Play issues, never a crash or no start. Game play is very good, almost excellent! Once you figure out how to play, its a blast. Graphics are good, and sound effects are great.”
“There is nothing quite like the feeling of a night-time surface engagement in this game. Watching the tracers fly and the searchlights cut through the dark is incredibly cinematic. It’s a slow burn, heavy on the…”

“even though this game isnt updated that much as i dont think there is a big company behind this game (correct me if im wrong i havent read about this game for a bit) it is a fun game well made and there are many mods…”
“This is a fun and good ww2 warships game, and with mods it can get to be lot more fun.”
“Super cool premise, I agree with others saying its a bit clunky(especially the UI). I recommend it because its a fascinating game that forces you to make critical decisions hours before they are fully realized, which…”

“So many clunky mechanics that don't even function like they did in real life alongside AI that fails to follow even the simplest instructions. If a game prides itself on being realistic, you'd at least expect systems to…”
“It's the worst custom/skirmish editor ever. Aircraft Carriers have no flight Deck and there is no evident way to launch planes if they are not in the air already. The UI is unintuitive and horrible”

“too much time wasted unpausing the game every ♥♥♥♥♥♥♥ day because the game informs you that air operations are again available. then you are interrupted again every ♥♥♥♥♥♥♥ time a plane appears near your base/base and…”

“Some parts of the game are incredibly cool, but the fundamentals of controlling your ships in combat are complex and absurd. Great concept but poorly executed. Terrible UI The campaign is a lot of fun. probably the…”

“This kind of Naval simulator based on big gun warship duels from both world wars is excellent and an continuation of the days of Fighting Steel from Microprose. But you do not have the ability to duel between all famous…”

“Great game with alot of potential. Only thing bringing it down is lack of campaigns”
— a player, Steam review · 74 hrs played“I enjoy the game but I have found that the Mac version is greatly dumbed down from the PC version, yet we pay the same price! So it's a mixed review. It's still worth the price for the Mac but just barely and only because the base game for the PC is phenomenal and you still get…”
— a player, Steam review · 1,541 hrs played“This game could be very fun, but one thing that absolutely ruins it for me is how accurate the AI is while my side cant land a single hit. Ill end up having 3 boats sunk before my ships land a single hit. spending 30 minutes watching my shells splash harmlessly nowhere near the…”
