UBOAT Review: Authentic to a Fault

Ultra-authentic, ultra-exhausting — when sim ambition starts to feel like shift work

Reviewed on PC.Score: 5/10

From submarine captain to overwhelmed player

UBOAT wants to be the ultimate WWII submarine simulator. In practice, it often felt less like a game and more like a second job. It isn’t an action-movie war fantasy, and it isn’t a breezy management sim either. It’s a relentless survival-simulation loop where a single missed task can sink an entire patrol. I respect the ambition, but the execution left me more stressed than satisfied.

The vibe: immersive, but exhausting

There’s no guiding story beyond what you make of each patrol. Atmosphere is top-tier—the cramped compartments, hull creaks under pressure, and that icy sonar ping do a lot of heavy lifting. But without characters or a narrative arc to latch onto, the immersion slowly turns into fatigue. The tension here isn’t the cinematic kind; it’s a constant hum of “what’s about to break next?”

Gameplay: a technical manual in disguise

Crew management: Keeping sailors fed, rested, and motivated feels less like commanding veterans and more like endless caretaking. Ignore a need, and the whole machine stutters.

Systems overload: Ballast tanks, fuel, engine modes, torpedo targeting—when multiple issues erupt at once, you’re buried in panels and micro-tasks instead of making meaningful decisions.

Combat pacing: Convoy attacks promise high drama, but too often devolve into long stretches of waiting punctuated by menu juggling and sudden failure.

Onboarding: Tutorials don’t meet the moment. Much of the learning happens through trial-and-error, which makes early hours feel like studying for an exam rather than commanding a boat.

What UBOAT nails

• Atmosphere and authenticity that sell the claustrophobia and dread of the Atlantic.
• Depth for hardcore sim fans who want granular control over every station and system.
• Clear identity: this is a crew-first survival sim, not an arcade shooter with torpedoes.

What dragged me down

• Micromanagement eclipses strategy—too many small fires, not enough big decisions.
• Weak tutorials create a “read the manual” barrier to entry.
• Combat and patrol pacing skew toward tedium, not tension.

Verdict

UBOAT is laser-targeted at a specific audience: players who crave uncompromising, systems-heavy realism and are happy to wrestle with it for hours. If that’s you, there’s a dense, demanding sim here. If you want something you can pick up and enjoy after work, UBOAT will likely feel like more work.
