About
Command the most advanced nuclear-powered submarines in the world. Modern Naval Warfare is the ultimate tactical simulation, offering unparalleled depth in graphics, physics, and authentic combat systems. From the pressure-crushed depths of the ocean to the high-stakes politics of the South China Sea, every bolt, frequency, and sonar ping is simulated with uncompromising detail.

Unrivaled Visual & Atmospheric Fidelity Experience a world built on real-world GIS data. The simulation's physically-based rendering (PBR) and world lighting create a breathtaking environment, from the curvature of the Earth at high altitudes to the shimmering caustics and reflections on the ocean surface.
Volumetric Clouds & Dynamic Weather: Navigate through GIS-assisted weather conditions and a multi-layered spectral wave system.
Authentic Interiors: Explore accurate 3D representations of the Virginia class (Blocks I-IV) CIC with fully clickable, feature-complete control stations.
Living World: Engage with digital twins of modern military and civilian platforms, including dynamic civilian traffic assisted by GIS-AIS data.
Advanced Acoustic & Physics Simulation In the silent service, sound is your only sight. Our 3D sound propagation model calculates transients, flow noise, and individual component sounds (engines, pumps, propellers) in real-time.
Real-time Signal Analysis: Utilize FFT analysis for Narrowband, LOFAR, and DEMON applications, modulated by specific sonar array characteristics.
Physical Realism: Every object follows real-time hydrodynamic and hydrostatic calculations. Weapons movement, explosions, and even material reactions to underwater pressure are physics-based.
Damage Control: Face hi-fidelity damage modeling and volumetric flooding based on true shipbuilding concepts like permeability.
Sophisticated Systems & Weaponry Take control of a wide spectrum of military-standard sensors, including RADAR, SONAR, and EO/IR.
Electronic Warfare: Experience RF signal propagation affected by wavelength, line-of-sight, and antenna configuration.
Lethal Arsenal: Deploy torpedoes, multi-stage missiles (with individual stage envelopes), and mines.
Countermeasures: Defend your boat with noisemakers, sonar decoys, chaff, and flares.
Navigation: Use INS, GPS/GNSS, Tercom, and DSMAC for precision strikes.

Step into the role of various crew members with native-language station interfaces:
Pilot Station: Control depth, speed, course, trimming, and masts.
SONAR Station: Manage Broadband, Narrowband, Active Intercept, and Tactical Decision Aid.
Fire Control: Utilize advanced TMA (Target Motion Analysis) with interactive rulers and mission planners for Harpoon and TLAM missiles.
ESM & RADAR: Intercept threats and monitor AIS signals to maintain situational awareness.

Whether you are a lone wolf or part of a strike group, the world is your battlespace.
The Technothriller Campaign: A massive 18-mission campaign set in the South China Sea.
Diverse Operations: Engage in Anti-Submarine Warfare (ASW), convoy hunts, special forces insertion, and espionage.
Training & Editor: Learn the ropes with a 3-mission training sequence or create your own challenges with the built-in quick mission editor.

This game is in early Alpha stage. Most systems are bugged, it suffers of performance issues (5080 and an I9 can barely handle 4x time compression) It has a lot of potential, but needs a few more patches to be playable.
THIS GAME SHIPPED WITHOUT AN ENEMY AI. THE AI WAS NEVER BUILT BECAUSE MATRIX FOCUSED ON THE MILITARY VERSION WHICH NEVER NEEDED AN AI. AND THEY CHARGE $59 FOR THIS GARBAGE. NOW THEY WANT TO MAKE AN AI? NOW???????? AND ALL THOSE IDIOTS ON YOUTUBE LIKE JIVE TURKEY MAKING PHONY VIDEOS, PRETENDING THEY ARE IN HUNT FOR RED OCTOBER WHEN THERE IS NO ENEMY AI AND NO ONE IS PURSUING THEM, THE MASLOS BROTHERS INTERVIEW ON YOUTUBE WAS A DISGRACE. SEND THIS TRASH BACK TO MATRIX. TAKE IT OFF STEAM
Sub sim fans were excited for MNW. Instead, we got a car crash. A screeching u-turn from full release to early access just days before launch date, resulting in a delayed launch as descriptions were hurriedly rewritten to conceal all the missing content and required branding was added. Sadly, this set the tone for everything that followed. No enemy combat AI whatsoever - they will not fire back or take any offensive action. They are only capable of defending. At release, combat AI was 'a week' away; now it's 'planned' for Winter '26. All that cool stuff in the trailer with ASW planes dropping torps on you? None of that is real. Abysmal performance even on high end systems, with next to no granularity in video options. Moronic mission design that has exercise targets steaming their merry way away from the exercise area in a random direction. Missions that don't work or can't be completed. Briefings that don't arrive, or are riddled with spelling and grammar errors. TMA autocrew that can't track a bulk freighter, let alone a submarine. Civilian yachts that don't sink after multiple MK48 torpedos. Utterly insufficient documentation. Serious terrain bugs like floating (and very solid) pyramids or underwater walls that rise vertically out of nowhere. Engine control bugs. And an awful community full of self-important blowhards that can't bear criticism. Lie after lie after lie from the developers. A Q&A that reeked of arrogance. A giant stain on Matrix' reputation. MNW is sunk before it even left port.
Excellent potential and I really want to like this sim, it promises to fill a niche that hasn't been for decades. But, and it is a significant one, this is both: a. very far from having a fleshed out gameplay loop, there is simply no "warfare" simulated at the current state, and; b. not in anyway justified in charging full price for the current state of the product.
unfortunatly at this time i deffinatly dont recommend this, i want to, i waited ages for this to come out, but at this timew there are so many bugs, no enemy ai, so like shooting fish in a barrel, constant problems with freezing etc etc, the level this is at now it will probably be a good year until its remotely playable, comments fall on deaf ears here on steam, as the devs never come n talk. look back in a year the the huge price tag for an ea maybe worth it
Because the DEVS work with the US navy, they apparently are not allowed to put any "realistic" functionality in the game at all. I'm very sad that this Sim will probably never be the "DCS" of naval warfare that we hoped. It most likely will be an unplayable mess until it is eventually abandoned.
This game was not ready for any kind of release, it has great potental but if you are on the fence about it, I would, as of today, recommend saving your hard earned money.
I really want this sim to make it out of Early Access and have it fully function. A lot of it does indeed work. But the moment you start moving things or dumping a lot of calculations with sonar it becomes obvious how fragile the sim engine is. It breaks under any real heavy data crunching. There is no enemy AI, mostly just training missions where you play around with the subs sensors to understand bearing and range. It needs way more time. Leaving EA in 2026 looks unrealistic. I really feel like a fool for spending the money.
Runs like a turd, but if they can fix the bugs and optimize it, it could be a great experience. I'll update my review when it's in a better state.
Been playing for many hours and have yet to be able to get the torpedoes to function properly without any success. I have had better luck with the HARMS. This game needs some in game tutorials or else have some sort of easy mode. Will go back to UBOAT at least it works. This game needs about another year of development. I would not recommend this game in the stage it is in. It is worth about $20 at this stage.
