What Steam players say
Recent verbatim reviews from Steam — separate from playze.io community reviews below.
Still one of the best submarine simulations of all time. Too bad content was limited back when it was made but they've patched it up enough to run smoothly even on Windows 11.1 found this helpful
classic, total classic
Can be difficult for some to learn but a very fun game
One of the finest Nuclear Submarine simulations in the world Based off the original code of Sub Command, the game/simulator started the submarine game genre along with Silent Hunter 1. Both came out around the same time and were both epic in their own right. Looking at 688(I) while playing it's stations, you get the feeling that the US Navy may come to your house and confiscate your PC because of the classified systems that this game and Sub Command revealed. 10 stars for this game still in 2026
its legendary fun, such an amazing community as well, this game is a classic for ASW geeks
Totally Awesome!
