Cheapest 688(I) Hunter/Killer keys — keyshops
Keyshops are third-party marketplaces — keys are resold and can be region-locked or a different edition. Check the listing's region & edition before buying.
Some stores inflate their “regular” price to show a bigger discount. We flag those (⚠ inflated) and show the real saving against the actual list price.
Some store links are affiliate links — playze may earn a commission at no extra cost to you. It never changes the price you pay, and the cheapest confirmed price is always shown in the Best price box above.

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 11.2 found this helpful
As a former RN submariner some features remind me of using the trafalgar class systems. A great game to play1 found this helpful
very realistic, take time to learn controlls and you will do well.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
