Reviews
- Engaging and fun cooperative submarine gameplay, especially with 3-4 players where roles like steering, sonar, and torpedo management create satisfying teamwork.
- Unique mechanics like crafting torpedoes mid-combat add strategic depth and tension, complemented by immersive sound design and distinct retro-dieselpunk atmosphere.
- Affordable price point offers good value for the amount of gameplay available, with solid core mechanics and a strong foundation for future expansions.
- Limited content with only a few missions and enemy/submarine types, resulting in a short overall experience that becomes repetitive after completion.
- Technical issues including frequent crashes, bugs (enemies getting stuck, desyncs), and poor performance optimization causing low framerates even on capable hardware.
- Annoying audio elements like loud torpedo crafting sounds and minor interface inconsistencies detract from immersion and user experience.
story
32 mentions Positive Neutral NegativeThe story aspect currently offers only three missions that mainly revolve around wave defense and survive-enemy encounters, with limited variety and some repetition. While the missions are described as entertaining and challenging, users consistently highlight a need for more diverse and content-rich objectives, additional missions, and potential community or procedural mission support to enhance replayability. Despite the limited story content, the game is regarded as fun and worth its low price, showing strong potential for future expansions.
“The missions are fun and actually difficult to do cleanly.”
“The 3rd mission is a wave defense mission in a very large and open area, which ended up being our favourite out of them.”
“Mission variety - the final escape phase was chaotic and exciting, but I’d love more complex objectives (e.g., stealth recon, timed extraction, or escort missions).”
“In the overall game, there is not much content, only three missions so far, which are mostly the same 'survive enemy waves' at the end of the day, which just maybe makes it worth the 5.19 euro price tag, but just barely, considering the game isn't marked as early access.”
“There are just 3 missions, and two of those are just 'go through this cave, kill the enemies at the objective, kill the enemies that spawn where you came from (and hope they didn't spawn in a wall making the mission impossible to complete)'.”
“You take on a single mission either alone or with your crew and try to make it through, that's all there is to it right now.”
