FULL METAL COFFIN 是一款 3D 合作潜艇模拟游戏，战场设在南极下方被淹没的洞窟深处。你们驾驶的潜艇采用最新材料科学打造，专门用来承受这片新环境带来的特殊条件。任务包括摧毁敌方前哨站，以及抵御一波又一波的来袭敌人。游戏带有架空历史、科幻和黑暗氛围的设定，水下环境和洞窟地形会直接影响你的行动。
最多 4 名玩家共同操作潜艇内部的各个系统。装填鱼雷、规避来袭火力、消灭敌人，这些都需要船员各司其职。你们可以建立明确的指挥结构，也可以自然地补位，哪里需要就去哪里。良好的配合与沟通会得到明显回报，协调顺畅的船员才能让潜艇稳定运转并压制敌人。
声呐和水听器机制做得比较深入：监听敌人的动静，把声呐脉冲打到洞壁上反弹，就能获得洞窟的更清晰视野。鱼雷可以针对不同情况制作出独特类型，造好后可以立刻装填，也可以先储存起来备用。面对前线的敌人，提前规划和深思熟虑是取胜关键，选择接战时机同样重要。
