What Steam players say

Recent verbatim reviews from Steam — separate from playze.io community reviews below.

✦ AI summary

War on the Sea offers engaging naval combat and logistics systems that players praise for their depth, but is hampered by inconsistent AI that frequently ignores commands and switches targets unexpectedly, making tactical control frustrating. Some players find the gameplay too passive and automated to maintain interest, while others appreciate the strategic elements when AI cooperates. Player opinions are divided enough that interested buyers might want to wait for reviews specific to recent updates before committing.

Not recommended Sep 20, 2026

Fun, but the AI SUCKS in all aspects! Trying to command anything in this game feels like trying to get a group of 10 year olds to focus on one thing. Ships and aircraft will randomly do whatever they want, lock/ unlock and switch targets. and ultimately it's nothing but frustrating.

fantastic game on all levels

Superb naval combat and logistics

Not recommended Sep 30, 2026

Frankly, this game is boring as hell. You can actually fire it up and go make yourself a cocktail and the ships will fight all by themselves. I found that Atlantic fleet was entertaining and engaging, the War on the Sea is not .
