    At first I really wasnt sure if this was going to be a big waste of time and money but to my surprise it can deliver a really entertaining time killer. THE GOOD 1: very realistic .. well at least to a civilian. 2: complex game mechaincs to those of us who dont like our games dumbed down. 3: strong sense of acomplishment when missions are completed 4: good variety of operations consisting of single missions, campaign and training. 5: A good challenge but far from impossible once youve…

    688(I) HUNTER/KILLER is an excellent game. I've been playing it for years. However....BEWARE Steam's version of this game as it is now bugged/unplayable...as of June 13, 2019. As Steam has no true customer service; per se, and absolutely no person you could actually speak with, I now have a great game that can no longer be played....and zero Steam 'support' to remedy the problem. ALL of us whom purchased 688(I) HUNTER/KILLER are now unable to play the game, thanks to a Steam auto-update…

    A classic in the submarine simulation genre. The missions may be canned - with no random variation aside from box patrols and units reacting to you - but the sim gameplay itself is great. When it came out, it pretty much blew the competition out of the water. You know, just like the ships in the game itself. The graphics and presentation are obviously dated, but still have a certain charm. You don't really play naval sims for the graphics, anyway. Just wait until it's on sale so you actually…

    This is a game that comes from a time when one had to have skill to win. If you like 90s graphics for explosions, a necessity to read online forums to understand the game's mechanics, and an overall love for strategey at sea; this is the game to play. I've been playing it since 1999, and I don't see a reason to stop.

    This is a great submarine simulation game. I felt right in the middle of the action, and there are definitely some tense moments, i.e. evading enemy torpedoes and stealthily sneaking up on an enemy submarine. The game has a steep learning curve at first if you've never played anything like it before. I recommend reading the captain's manual if you want some early pointers on how to learn the basics. Some of the missions take multiple hours to complete, and I found it easy to lose myself in…

    If you like submarins, this is a nice game to learn all about them. The drawback is TIME. Everything goes so slowly and, you are so blind that the game can be really frustrating. Maybe a good simulation but, a game needs something else to be attractive to the player. Buy if you like submarins and the price is a bargain

    This is an extremely old game based on a submarine simulator in a war scenario. You are essentially taking control of a submarine in midst of combat. It is definitely not a game for everybody. It is a realistic simulator of what a person in a submarine needs to do in order to survive and fight. It isn't your casual arcade game where you're controlling a submarine from the outside swimming around blowing up battleships. It definitely takes a while to get used to because there's a lot that…

    It lacks an in depth tutorial and there's not much to be found online regarding gameplay mechanics. Once you get the hang of it, it gets fun. Expect to spend 10 hours or so getting the hang of it, if not more. This game is fairly bug-free. It has a campaign which is 'ok'. The campaign debriefings are intentionally cheesy, I think it sort of loses some realism there but it's also a bit funny, so it's a wash. It could stand to use some extra features that were included with the sequel, Sub…

    I don't know how I got this. I hope I didn't pay for it. I guess if you have nostalgia for it go right ahead but it's as intuitive as a 16 year old game and the graphics are fit for 1997. Steam overlay doesn't work which means you can't take screenshots or use any community features.

    Why should you buy Jane's 688(i) Hunter/Killer: It was one amongst few modern submarine simulation available at the market and ofcourse one of the best, if not THE best. This sim is all about processing data which you receive from your various sonar sensors at your 688 improved Los-Angeles class attack submarine. You should really ignore the graphics in these kind of sims because of the fact that you sit inside a steel tube trying to listen for enemy surface threats, evading them in order to…

    What we have here is a great attempt at making a submarine simulator that was novel enough when it was made that the average player did not really notice its flaws, but over time these have become extremely noticeable. I tend to put "688 Hunter Killer" into a category of games with "L.A. Noire", "Tropico" and "Assassin's Creed" which I credit with reaching very high with a new concept, and almost making it. The problem is that most missions are either too easy or too hard. Any mission with…

    1: Spend a few hours reading the manual and doing tutorial missions. 2: Spend half an hour staring at sonar while trying to figure out what you're looking at- 3: Fire a torpedo and make evasive maneuvers. 4: Wait 15 minutes. 5: Realize you tried to sink a whale. 8/10, very slow but also very satisfying in the end.

Now finally I can play this game on my computer again. It is just as I remembered, a hard core submarine simulator. Very accurate to how to actually use sonar and ship manuvers. I have had my navy friends help me in this game learn how to use the sonar and launch torpedoes. This is a great game and a lot of fun. You just have to be patient and…

    I played Sub Command during my undergraduate years and was hooked to it. Played it all night long every Saturday at my dorm. I then bought Dangerous Waters which improved upon it. I never tried 688(I) Hunter/Killer although I heard it was an excellent game. That is until today. On my first try I fell in love with it. The gameplay feels better than both Sub Command and Dangerous Waters primarily due to the better interface design. They even put 3D layout of the submarine interior and a 3D view…

    The fact I got so much enjoyment out of this hardcore nuclear submarine simulator is how I know I'm getting older. Reading of the beefy manual is mandatory if you want to so much as submerge this thing. It'll be a while before you get comfortable with the controls, and even then it's a good idea to keep the manual handy. It's a game from 97 so the 3D graphics are very quaint, which does not mean they skimmed on the details. Moreover, the immersive audio design is doing most of the legwork in…

    Calling 688(I) a game is unfair; this is a true simulator. As such, it's definitely not for everybody. There are very few accommodations made for the sake of gameplay here. This isn't a sub game where it's blazing action at all times, with subs that behave like speedboat/fighter jet hybrids. No. Submarine combat is a matter of skulking around in the dark, moving cautiously, listening, and above all, patience. About the only "gimme" for the sake of gameplay is the inclusion of a "speed up"…

    This is a simulator sub marine game which is kind of outdated in graphic and gameplay. Its hard to just pick up and learn this type of gameplay right away but after time you might get a hang of it. Its a game were you pretty much find the enemy and try to kill them before they kill you. The graphics are old and kind of blocky. The music I had to turn off because it was kind of getting annoying. Its an alright game. If you get it in a pack then that's the best way to obtain a game like this.

    Although old, 1997, it is the most authentic submarine game ever. You need to be patient and willing to learn a lot of info and how to act upon it. If your looking for a submarine shooter game, this is not for you. If you want to learn a lot about commanding a sub, learning sonar, TMA and fire control this is the game. Be prepared for a long game.

    This is a submarine simulator, where you play as the Captain of an Improved 688 attack sub (Los Angeles-class). Move silently, strike deadly. Your opponents can be a number of enemy platforms from the late 90’s. At least, as far as I can tell, since there seem to be some missing Soviet/Russian naval units, which might have been retired at that time. Controls are not intuitive, and will take some getting used to. Suggest buying in the bundle, since there are quite a few decent games within.

    Steep learning curve (doubly if you don't know your Navy shorthand), but with buttons that actually do stuff, and a way of controlling that can't be mapped strictly to a gamepad (moving to different "posts")...they don't make games like this anymore. I miss this. Though it's slow paced as an experience (and crashed once for me), I absolutely admire the 90s graphics and the soundtrack (we need more like that, with this kind of "tension" and "intensity"). Also I swear the map is both bigger and…

    Immerse yourself in the life-and-death pressure of an authentic 688(i) Los Angeles class nuclear attack sub. Developed by actual U.S. Navy Defense contractors, Jane's dead-on combat sim pulls you deep into the depths of intensity. Critical operating systems include weapons control, sonar suite and target motion analysis. With multiplayer capabilities the only question is, how long can you hold your breath?

    Such an old game - but still runs on Win10 without issues. Graphics are obviously extremely outdated, but the gameplay hasn't changed. It's still a great sub sim, if you like those stealth games that don't work with just visual input. Unlike many modern sub games, it's not just an underwater "flight sim", but a game mostly about staying undetected. Still recommended. If you know what to expect.

    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

    It looks different but reminds me of a mission editor of Jane's 688(i) Hunter/Killer, a 1997 submarine sim I played as a kid. I may still have the CD somewhere.😁 Oh, or the SU-27 Flanker mission editor. There are probably quite a lot of them but these two are the ones I remember rn for some reason.😭
